A larger RAID rackmount system.

RAID 6 offers a higher level of fault tolerance than RAID 5 because it can survive the simultaneous failure of two hard drives without losing data. RAID 5 is popular for its balance of performance and storage efficiency, but RAID 6 provides the extra security necessary for high-capacity storage environments where drive rebuild times can take days. 

Below, we’ll compare the architectures of both levels to help you decide which configuration will work best for your needs. First, though, we need to clear up a common point of confusion: RAID is not backup, and should not be used as the sole means of protecting data integrity. Here’s why.

Why Choose RAID At All?

RAID stands for Redundant Array of Independent Disks, or alternatively, Redundant Array of Inexpensive Disks. A standard RAID combines multiple physical hard drives into a single logical unit to improve performance or provide redundancy. 

(Note: Despite the name, RAID 0 isn’t truly redundant — a single member failure will cause data loss — but we’ve discussed RAID 0 in detail in another article). 

Redundancy is the primary benefit for most businesses. By spreading data across multiple disks, the system remains operational even if a hardware component fails. Obviously, that’s essential for mission-critical systems (servers, for example). 

But RAID is not a substitute for a backup. It’s a safeguard against hardware failure, it does not protect against accidental deletion, file corruption, ransomware, or multiple hard drive failures. Always keep a separate, off-site backup of your critical data.

The Advantages and Use Cases for RAID 6

RAID 6 utilizes dual parity, which means it calculates two different sets of parity data and distributes them across all disks in the array. A minimum of four drives is required for this architecture.

With RAID 6, you get a few clear advantages:

• Tolerance for Double Failures: The defining feature of RAID 6 is its ability to withstand two concurrent drive failures. In our laboratories, we frequently see cases where a second drive fails during the high-stress rebuild process of the first failed drive; RAID 6 prevents this from becoming a data loss event.
• Suitability for Large Drives: As hard drive capacities grow into the terabytes, rebuild times increase significantly. RAID 6 is the strategic choice for large arrays where the window of vulnerability during a rebuild could last 24 to 48 hours.
• Enterprise-Grade Reliability: RAID 6 works better for mission-critical servers and data archives where uptime is paramount and the cost of extra disks is secondary to the safety of the information.
• High-Read Environments: Like RAID 5, RAID 6 offers excellent read performance, so it’s well-suited for database servers and applications where data is accessed frequently by many users.

The Advantages and Use Cases for RAID 5

RAID 5 uses single parity distributed across all disks and requires at least three drives. It remains one of the most common configurations for small-to-medium business NAS (Network Attached Storage) devices.

RAID 5 is relatively common, which gives it an immediate advantage — it’s far easier to find resources for RAID 5 arrays, both in terms of setup and disaster recovery.

Other advantages of RAID 5:

• Optimized Storage Capacity: Because RAID 5 only uses the equivalent of one drive’s capacity for parity, you have more usable space compared to RAID 6. If you are working with a limited number of drive bays, RAID 5 maximizes your investment (this isn’t really much of an advantage given the historically low cost of hard drives, but it’s functionally important at scale). 
• Faster Write Performance: RAID 6 requires two parity calculations for every write operation, which can create a write penalty or performance lag. RAID 5 only performs one parity calculation, so it’s typically faster during writes.
• Cost-Effective Redundancy: For smaller arrays using lower-capacity drives, the statistical likelihood of a second drive failing during a rebuild is relatively low. RAID 5 provides a balanced safety net without the hardware overhead.
• General Purpose Storage: Small-scale file storage, web hosting, and development environments often benefit from RAID 5 where a single-drive failure is a manageable risk. 

For a deeper look at the mathematical probabilities of drive failure, the Storage Networking Industry Association provides extensive research on system reliability and data management.

Selecting the Right Configuration for Your Data

Choosing between these two levels involves a trade-off between capacity and redundancy. For most use cases, capacity and write speed win — RAID 5 is the most popular option for small-scale storage for a reason.  

With that said, RAID 6 is the right choice for high-capacity arrays where data integrity cannot be compromised. If your rebuild window exceeds several hours, the dual parity of RAID 6 protects against catastrophic rebuild failure.

While we don’t make many hardware recommendations, we do see hundreds of RAID, JBOD, and NAS/SAN systems each year. When clients ask our engineers to recommend a reliable, functional, and cost-effective storage device, we recommend JetStor solutions from AC&NC.

Our reasoning is simple: These devices are extremely reliable systems. They’re typically customized for specific storage needs, which has significant advantages in terms of speed and reliability. In modern applications, customization is crucial.

JetStor engineers assess application requirements carefully in order to build storage devices that offer a blend of functionality and scalability, and from the systems we’ve seen in our laboratories, they do a tremendous job of addressing their clients’ needs.

The Advantages of a Custom JetStor RAID

Because AC&NC builds JetStor storage solutions for dozens of applications, they offer expansive options, including custom SAN, NAS, DAS / SAS, and JBOD options. This is crucial, because two different applications will often require two very different approaches—and one company’s ideal RAID setup may expose another company to data loss or unnecessary expenditures.

JetStor systems vary greatly in terms of size and RAID configuration, so levels of redundancy vary. Some JetStor devices can sustain several physical media failures without losing data, while others don’t have this same level of protection. A company might opt for less redundancy in order to reduce costs, or to increase storage capacity without increasing the physical size of a storage system.

But even when redundancy isn’t a major concern, JetStor devices are very reliable thanks to high-quality hardware. AC&NC recognizes that redundancy isn’t the same thing as a backup—any system can lose data, regardless of the quality of its components.

Even with safeguards, data loss is always possible in extreme circumstances, but AC&NC goes above and beyond in using best-practice techniques to create dependable systems. They actively educate their clients, clearly explaining the benefits of different RAID levels and backup techniques. That results in a great return on investment, regardless of application.

JetStor offers expert support, and their staff can effectively address some disaster recovery scenarios. Additionally, many JetStor solutions incorporate offsite backup without relying on data tapes, and incorporating best practices to ensure dependable access to crucial files.

Datarecovery.com regularly works with AC&NC hardware, and we often recommend them to our clients as replacements for inferior storage systems. We’ve also performed RAID data recovery services for JetStor owners on occasion, and we’re impressed by what we’ve seen.

Every company that relies on large physical storage systems should invest in custom solutions to see the best possible results. We strongly recommend AC&NC and JetStor in these instances. Click here to visit the JetStor website.

Synology Data Recovery for Disaster Scenarios   

Thousands of enterprises worldwide rely on Synology products for large-scale storage. In 2011, only Netgear and QNAP shipped more units than Synology, which controlled an impressive 13.4 percent of the global market.

With top-rated models suitable for any level of storage, Synology RackStations and DiskStations provide dependable service for home and business users. The company offers optional RAID storage on all of its products with multiple HDD trays, and many RackStations ship with standard RAID configurations in place.

However, even with the distributed parity of a RAID 5 configuration or mirrored block redundancy, no storage device is 100 percent fault-tolerant. Synology NAS devices are not immune to component failure, and rebuild errors are always a danger for certain RAID levels.

 Some of the more common causes of data loss for Synology DiskStations and RackStations include:

• Server Hardware Failure – Higher-end RackStations include redundant power supply units, but most Synology NAS rely on a solitary component to drive power, and power units are not the only single point of failure in Synology servers. Any component may fail unexpectedly, and hardware failure can place data at risk.

• HDD Failure – Synology RAID is designed specifically for fault tolerance, but losing a single HDD places greater stress on remaining drives in the system. Running RAID arrays in a degraded state may lead to further disk failure, risking your files. Physical damage, such as fire, flooding, or magnetic exposure, may also cause multiple drive failure in Synology RAID arrays.

• Software Errors – Synology servers ship with a proprietary operating system called DiskStation Manager, which can develop system errors. When not sufficiently secured, older versions of DSM may be vulnerable to hacking attempts or software failure that limit access to your files.

Human error can also damage software functionality, particularly during RAID disk rebuilds.      

Synology RAID is not immune to these hazards, but when disaster strikes, depend on Datarecovery.com. Our engineers have been working with Synology servers since they became available in 2000, and we continually develop expertise with the company’s advancing technology, from SSD cache read/write support to the latest version of Synology DiskStation Manager.

The issues primarily affect Seagate and LaCie wireless storage products, especially the Seagate Wireless Plus Mobile Storage, Seagate Wireless Mobile Storage, and LaCie FUEL.

Firmware versions 2.2.0.005 and 2.3.0.014 are known to be affected by the vulnerabilities. However, other firmware versions may be affected, according to CERT/CC (Computer Emergency Response Team Coordination Center), the federally funded organization that announced the discovery of the flaws.

To check your firmware version, you can load the Seagate Wireless Plus menu in your browser and select the appropriate option from the Settings -> About menu.

The vulnerabilities are as followed (the following text is taken directly from the CERT announcement):

CWE-798: Use of Hard-coded Credentials – CVE-2015-2874

Some Seagate wireless storage products provide undocumented Telnet services accessible by using the default credentials of ‘root’ as username and the default password.

CWE-425: Direct Request (‘Forced Browsing’) – CVE-2015-2875

Under a default configuration, some Seagate wireless storage products provides an unrestricted file download capability to anonymous attackers with wireless access to the device. An attacker can directly download files from anywhere on the filesystem.

CWE-434: Unrestricted Upload of File with Dangerous Type – CVE-2015-2876

Under a default configuration, some Seagate wireless storage products provides a file upload capability to anonymous attackers with wireless access to the device’s /media/sda2 filesystem. This filesystem is reserved for file-sharing.

Read the full report here.

These are significant security vulnerabilities, since they could allow an attacker to access a wireless Seagate or LaCie device. The attacker could then read, change, or delete files from the hard drive.

According to Seagate, “affected users are encouraged to update the firmware as soon as possible.” The revised firmware can be downloaded from Seagate’s website. CERT also recommends the firmware update as a solution.

As with any firmware upgrade, we strongly recommend backing up data before starting the update process. Data loss can occur if the update is interrupted for any reason. Users should also review passwords on any network-attached storage device to ensure security.

A Brief History of the Seagate BlackArmor NAS

The BlackArmor series is designed for backup and centralized storage, with features that focus on improved file access and sharing. It also allows access from outside of your local network — you can store files on the NAS and access them from any computer with an Internet connection.

Some models are branded under the Maxtor name (Maxtor was a major hard drive company that was acquired by Seagate). BlackArmor split off from the popular OneTouch line of external hard drives, which was marketed by Maxtor, and some of the models have similar features. This series is one of the most popular consumer-level NAS technologies available.

At the time that this article was written, the following Seagate BlackArmor NAS devices were available:

• Seagate BlackArmor NAS 110 – One hard drive. No redundancy.
• Seagate BlackArmor NAS 220 – Two hard drives. Supports RAID 0 / RAID 1.
• Seagate BlackArmor NAS 440 – Four hard drives. Supports RAID 0 RAID 1 / RAID 5 / RAID 1+0.
• Seagate BlackArmor NAS 420 – Two hard drives. Supports RAID 0 / RAID 1.
• Seagate BlackArmor NAS 400 – Does not ship with any hard drives. Supports RAID 0 RAID 1 / RAID 5 / RAID 1+0.

This may not be a complete list, and Datarecovery.com offers NAS recovery for all models. This article will focus on devices that use RAID. Some models contain a single hard drive and are covered under our standard hard drive data recovery services. Every standard case receives a free evaluation, however, regardless of the number of hard drives.

Potential Types of Failure for Seagate BlackArmor Devices

By default, four-drive BlackArmor NAS systems use RAID 5 configuration to provide redundancy (if one drive fails, the device will run in a degraded state, but it will not lose data). Two-drive BlackArmor devices use RAID 1 by default, also known as a mirrored RAID. In a mirrored RAID, both hard drives contain the same data.

For a BlackArmor NAS running RAID 1 or RAID 5, common data loss scenarios include:

• Hard Drive Failures – Multiple hard drive failures will cause data loss. Signs of hard drive failure on a BlackArmor NAS will vary by model.
  
  BlackArmor devices with an LCD screen will display an error message denoting the hard drive failure. If you have installed BlackArmor Manager, a web event occurs, which prompts an error message. Depending on your configuration, you may also receive an email notification. Finally, you can manually check whether a drive has failed in BlackArmor Manager’s Storage by selecting “Disk Manager.”
  
  As with any HDD-based device, turn your NAS off immediately if you hear loud mechanical noises that could indicate a hard drive failure.

• Rebuild Errors – You may experience a rebuild error if your NAS fails or loses power during a rebuild, which can result in data loss. Never replace a damaged disk with a disk that was previously used in another system. Always use a completely new drive that is the same size as the old drive. Do not change the order of the drives in the hard drive bays.
  
  If you do experience a rebuild error, do not attempt data recovery on your own. Rebuild failures can cause extensive fragmentation, and you will need the services of a professional data recovery company.
  
  One of the most common rebuild errors includes the error message “Seagate booting,” which never changes. This is usually caused by a single damaged hard disk drive, but because rebuild errors can result in data loss, we recommend seeking assistance from data recovery professionals if you experience this error (unless the error occurs before important data is written to the NAS).

• Electronic Issues – The actual BlackArmor enclosure may fail, which will prevent you from accessing your files. The hard drives inside the enclosure often remain in working condition.
  
  This is typically a very easy recovery, but we recommend taking the array to a professional data recovery company in order to avoid potential issues (accidental overwrites during a rebuild, for example).

Two simultaneous hard drive failures are unlikely, but possible, and rebuilding a damaged RAID can put additional stress on hard drives that will prompt a failure. Multiple hard drive failures usually occur as a result of electronic damage.

Datarecovery.com operates real laboratories across the United States. Our NAS data recovery experts can help you find appropriate solutions for any BlackArmor error, and we provide a no data, no charge guarantee with every case.

An MMS File System Data Recovery Guide from Datarecovery.com

Datarecovery.com can recover the data from all models of Maxtor shared storage devices. In most cases the disk(s) inside have failed, and the device requires treatment from a company with a minimum Class 5 clean room. If you believe this is the case, please call us at 1.800.237.4200 to set up a free consultation.

If you have a Maxtor Shared Storage NAS device with failed electronics, but you can verify that the hard drives are fully operational, you may be able to easily recover the data.  This guide explains how to mount the drive on a Windows box.

DISCLAIMER: This information is provided for technically experienced persons. It is provided without any guarantees.  We do not provide technical support for any Maxtor Shared Storage data recovery attempts.  Use this information at your own risk.

To limit your chances of permanent data loss, always make two full images of your drive(s) before modifying a volume. If you cannot make images of your disks, we do not recommend carrying out the steps listed in this guide.

If you are not experienced with hex editors and other technical tools, we do not recommend any attempt to recover your own data.  Call 1.800.237.4200 for expert assistance.

Read through this entire process before performing any of the steps listed below.  This procedure assumes that you are running a Windows operating system.

1. Make two complete clones of every drive in your Maxtor Shared Storage device.

1. Use a hex editor (free options include Winhex) to view the first partition of your disk.

2. Download and replace the first sector (sector 0) of your MMS disk with our modified boot sector. This is a standard boot sector modified for the normal setup of a Maxtor 500GB shared storage drive.

After you have completed this step, you are done making modifications and can go on to step 4 unless your shared storage device is not a 500GB model, in which case you will need to go to step 3.

3. Sector 1 of your disk contains the necessary partition information such as the partition offset and size. We have identified exactly which bytes need to be modified in the MBR (sector 0). Do not modify any other sector. Because the MBR stores data in the little-endian format, each 4 bytes that we identify in sector 1 will need to be reversed in the MBR partition table.

Examine both the MBR and sector 1 below. You will notice how the data is copied into the MBR. We have color coded each block of data that you need to copy in sector one, reverse, and copy to sector 0.

4. Mount your disk using rfsgui v2.2 (freeware) or Total Commander file manager with the reiserfs plugin ex2fs. There are other utilities that will mount a Reiser Partition; use these programs at your discretion. Copy your data to complete the process.

If you still cannot access your data, you may need assistance from a professional data recovery company.  Call 1.800.237.4200 to get started.

Nevertheless, data recovery cases are often received in which rebuilds or server changes were improperly handled, resulting in some form of data loss and even overwritten data. This can be catastrophic for IT departments, as the NAS and RAID systems offered by Aberdeen often hold terabytes of vital information. As such, we treat every data recovery case on a Aberdeen LLC device as a priority. Even in extreme cases, our experience in the field and knowledge of the various file systems used by Aberdeen LLC has led to a high recoverability rate, even when data has been partially overwritten.

Recovery Process for Aberdeen Devices

Data recovery on Aberdeen LLC devices typically involves two phases: a standard hard drive recovery phase (if data has been lost due to a hard drive failure), followed by a specialized approach to rebuild each system of drives in the correct order to recover intact data. This second phase is addressed on a case by case basis, as the high level of specialization in Aberdeen LLC devices makes a universal data recovery plan impossible.

Only high-level engineers with experience with RAID, NAS, and various other multi-drive arrays are allowed to work on Aberdeen LLC devices, and we work closely with our clients to develop a plan based on the operating system, file system, the exact cause of the failure, and other variables. Many modern Aberdeen LLC devices use VMWare virtualization software, and Datarecovery.com engineers are leaders in VMWare recovery techniques. You can read more about our techniques and capabilities for VMWare systems by speaking with a member of our data recovery team – call 1.800.237.4200 to get started.

Remote Recovery Options for Aberdeen Data Recovery

Because of the high level of complexity involved, some Aberdeen LLC cases are recovered onsite. This is especially true when a hard drive failure caused the data loss. However, in many instances remote recovery is possible, although the possibility of remote recovery needs to be directly assessed by a data recovery engineer.

Remote recovery requires secure, block level access to the array or NAS. Engineers connect to the system, repair damaged VMFS volumes or other volumes dependent on the operation and design of the device, and allow the volume to be easily mounted. This process minimizes downtime and can sometimes be completed in only a few hours.

Supported Aberdeen Devices

Datarecovery.com supports recovery on the following Aberdeen LLC devices. As data recovery techniques are constantly improving, it’s impossible to list every recoverable system, and recovery techniques will vary for different devices. Contact us to speak to an engineer for an estimation of your case’s cost and the likelihood of recovery.

Please note that this is not a complete list.  We currently offer data recovery services for all Aberdeen storage systems.

The RAID arrays and NAS & SAN devices sold by Sun and Oracle are built with a high degree of redundancy and superior hardware, but as is the case with all servers, data loss is possible.

Our data recovery engineers are specially trained to work with Sun and Oracle servers, and have specific experience with the Solaris operating system as well as the other operating systems that the servers use to operate. Datarecovery.com engineers are able to obtain full data sets from the vast majority of Sun server cases.

Our Detailed Data Recovery Process for Sun Servers

Every Sun server is different, and our data recovery process is substantially different in every case.  When you call 1.800.237.4200, an engineer will speak with you to determine the best course of action for your server.

Remote recovery is often the fastest option. This allows your system to be re-mounted and used normally after recovery is complete, and your hardware remains at your physical location. An engineer connects to your server through remote software with bit-level access. We correct errors and use logical procedures to return the server to its original condition, and downtime is minimal.

Some Sun NAS devices and RAID arrays have issues that must be addressed in-lab. This is most common in instances where a power surge or misconfiguration led to the failure or corruption of several drives. In these cases, we recover the damaged media in a Class 5 clean room using advanced data recovery techniques. Clones are made of the failed drives to ensure the best possible results, and data corruption is addressed with specialized software.

Speak to an engineer at 1.800.237.4200 to discuss recovery options for your case.

Sun Server Error Messages And Symptoms

There are numerous symptoms that could indicate data loss on a Sun server. Primary indicators are LEDs and Solaris GUI alerts that show failure of more than one hard drive (enough drives where built-in redundancy doesn’t prevent data loss). If LEDs on your Sun server indicate power failure or a poor operating environment despite contrary conditions, you should contact Sun customer support or speak to a recovery engineer as soon as possible.

Configuration issues can also make data inaccessible, and these can be a major concern. “Error executing server” is one example, but this can have a simple or complex solution; it simply indicates that the server is unable to operate. These types of “Unknown” errors on Sun servers generally indicate some type of hardware failure which prevents the server from starting up properly.

You should take enormous care when addressing configuration issues, as it’s possible to complicate even simple problems on high-end servers with minor missteps. Engineers at Datarecovery.com can determine whether your Sun server’s error messages indicate a need for data recovery.

Sun Sparc Server Data Recovery Tips

When you speak to a data recovery engineer, be sure to have as much information as possible regarding the symptoms that led to data loss. You should also try to collect information about the operating system, file system, the number of drives in the NAS, RAID, or SAN, and any other information that might be relevant to the process.

Do not attempt to run your server after data loss occurs. Never reinitialize a server with multiple failed drives without contacting Sun Microsystems or a trained data recovery engineer.

Most Sun server cases result in a full 100% recovery of requested data. By acting quickly, the chances of recovery are improved and cost and turnaround time are reduced dramatically.

The Netgear ReadyNAS* is an innovative series of network attached storage (NAS) devices designed primarily for small offices and home computer users. ReadyNAS is remarkably powerful and reliable, despite its entry-level price tag, and the series is popular for its automatic syncing, ease of use, and built-in RAID protection.

Successful Netgear ReadyNAS* data recovery involves a detailed understanding of the Linux XFS, EXT2, EXT3 file system structures along with the standard and custom RAID parity algorithms used by these devices. Oftentimes data loss situations involve corruption of the file system, causing loss of access to all of the files on the device. Multiple disk failures can also cause data loss, despite the redundancy offered by ReadyNAS RAID options.

Datarecovery.com can restore corrupt file systems, replace damaged media, and recover all of the data from your Netgear ReadyNAS, providing fast results through our full-service laboratories in the United States and Canada.

Key features of our Netgear ReadyNAS* data recovery services:

• File System Support – We have specialized data recovery solutions for all file systems used with the Netgear ReadyNAS*, including (but not limited to) EXT2, EXT3, EXT4, and XFS.
• Simple Data Return Options – Datarecovery.com’s engineers can copy all folders to a dedicated external hard drive formatted with the same file system as your original media. In many cases, we can return small files via FTP, giving you immediate access to important data.
• On-Site Solutions – While our in-lab services are the most affordable option for home computer users and small businesses, we also offer on-site RAID data recovery for all devices. Call for more details.
  Remote recovery is not an option ReadyNAS* due to the high risk of automatic fsck engagement and RAID rebuilding.
• An Excellent Track Record – We have performed data recovery services on all Netgear ReadyNAS* systems, and our services feature success rates of over 95 percent. We can also provide references upon request.
• Multiple Locations – Each of our laboratories is outfitted for RAID data recovery.  More lab locations means faster turnaround times and higher success rates for our ReadyNAS* customers.

Because the ReadyNAS* can start rebuilding as soon as it is powered on, we recommend keeping your RAID completely unplugged until you can speak with a data recovery specialist.  24/7 services are available for emergencies, and Datarecovery.com provides a no data, no charge guarantee with every ReadyNAS* data recovery case.
