You may be using a RAID storage system for speed, data redundancy, or a combination of both. However, RAID drives are still susceptible to data loss. Due to the relatively complex nature of these storage systems, RAID data recovery is trickier than standard hard disk drives. It’s important to choose a good RAID data recovery program if you want to safely recover data from a RAID array.

Specifics of RAID Data Recovery

RAID data recovery significantly differs from regular data recovery from a hard drive or SSD. In most cases of data loss in a RAID, you will need to rebuild the RAID drive to its original parameters. This can be done by using specialized software or using professional help.


Note: If your RAID is completely inaccessible, it’s recommended you contact a professional data recovery service. A failed RAID rebuild attempt will cause further data loss.

A crucial step in RAID array recovery is knowing which RAID level are you using. The most common RAID configurations include:




RAID 0 works on the principle of “striping” data across multiple disks, i.e. data is split across the drives, resulting in exponentially fast read and write speeds. While this is good for performance, RAID 0 doesn’t offer any data redundancy because even if one of the drives fail, all your data is rendered corrupt and inaccessible.


A RAID 1 array mirrors the data on your drives. Essentially, your data is copied exactly as it is to all the drives in the RAID array, making RAID 1 excellent for data redundancy. A major drawback is that users only get half the effective storage space at double the cost.


A level 5 RAID array stripes your data across the drives. In addition to that, it stores a parity checksum, a sort of integrity check for the data, on a separate drive. This allows the data to be striped across the hard drives, while providing data redundancy in case one of them fails. You need at least three hard drives to set up a RAID 5 array.


A RAID 6 array works on the same principle as RAID 5. However, it uses two parity blocks to keep a check on the data. This means that a RAID 6 array can survive two hard disk failures without losing data. RAID 6 requires at least four storage drives in order to work.

RAID storage systems either use a software or a hardware controller to ensure the RAID arrays work together. A common reason behind RAID data loss is a corrupt or failing RAID controller. One telltale sign of this is data loss, even though all individual drives are in full working order.


Some RAID enclosures come with an eSATA or USB interface that lets them connect directly to a PC. But, if the RAID array is damaged, not detected by the PC, or there’s no compatible connection interface on the enclosure, you will have to manually rebuild the RAID array. The RAID rebuild process will take place on the PC you’ll use to perform RAID data recovery.

What Is Nested RAID

Explained above, are the basic RAID levels. But, you can combine two different RAID types according to your specific use case. This is called a nested or hybrid RAID. While there are various hybrid RAID types, the most common one is RAID 10 (RAID 1 + RAID 0).

RAID 10 combines the mirroring of RAID 0, with the data striping of RAID 1. A RAID 10 setup requires four disks and can survive two failed disks. Due to their nature, nested RAIDs require more number of disks than their regular counterparts.

Other nested RAID types include RAID 50 (RAID 5 + RAID 0) and RAID 60 (RAID 6 and RAID 0), which require a minimum of six and eight storage drives respectively.

Top 7 Best RAID Data Recovery Tools

RAID file recovery is complex, which makes it imperative that you choose a RAID recovery tool that caters to your particular RAID type and data loss scenario.

  • Can create disk images.
  • It has a file preview feature.
  • Small installation size.


  • Only works on Windows 10 and above.
  • Limited file system and RAID level support.


Here is a quick guide on how to recover files from a RAID array:

  1. Download and install Disk Drill.
  2. Connect the RAID set if possible, else connect the individual drives to your computer.
  3. Open Disk Drill, select the drive and click Search for lost data.
  4. Click Review found items.
  5. Select the desired files and click Recover.

It’s difficult to find good free RAID recovery software, so be prepared to shell out anywhere from $50 to $899, depending on the program. Professional RAID data recovery services are substantially more expensive, ranging from $300 to more than $2000, depending on the severity of the data loss and the complexity of the array.

No, it’s recommended you use good data backup tools to back up your data separately to other storage drives as well as the cloud. RAIDs can serve as an added protective measure.

Different RAID levels serve different purposes. Selecting the best RAID level will depend on your specific needs, and the usage scenario. You can take advantage of nested RAIDs to get the best of both worlds, but be prepared to spend more money.


It’s important to choose a good RAID data recovery program due to the cost and importance of data involved in RAID arrays. Additionally, remember to act as quickly as you can because multiple drives failing one after the other is not as rare as you may think.
