RAID Data Recovery is one of the specialties of the array of data recovery services offered by WeRecoverData.com. RAID is a great system for increasing speed and availability of data as it offers considerably more data protection than non-RAID disk systems. However, its management of the disks and the data distribution across them can be extremely complex. (Learn more about RAID)

WeRecoverData.com - Data Recovery Lab has extensive experience RAID Data Recovery from RAID, spanned and striped systems.
- We only normally require just the storage devices in order to recover lost data.
- No matter how well designed or implemented the system is, there is still one very complex factor that causes the most RAID failures we see – the human being.
- Mistakes are easy to make and the more complex the systems become, the more potential there is for mistakes to occur.
- Using our disk recovery processes, coupled with our ability to produce a safe 'copy' of the complete volume, allows us to process an array as a collection of image files enabling fast and easy RAID data recovery.
- Our Data Recovery systems have the capacity to absorb most server array volumes. Recover RAID with the industry leading RAID Data Recovery provider.
" All our data is fully restored, and we're back to normal. Thanks so much for saving our business!
We were in the middle of changing our office domain, and our main file server went down, evidently a physically damaged RAID. Then we discovered that the tape backup had not been functioning properly, so we'd lost about 5 month's work. One of the things the disc had contained was a huge database for our major client (The Coca-Cola Company 
) , and it was almost time to deliver it to them. If we couldn't get our data back we would almost certainly go out of business.
We called the lab and took the server in for data recovery. They worked on it for over a week, and in the end recovered all the lost data. Needless to say, we have everything double backed-up now. "

RAID Data Recovery / RAID Failure / Recover RAID- FAQs
Q: We Re-striped/Re-Initialized the RAID array formatted the array and copy data back to it, Is there a chance of recovering the data before the Re-Striping/Re-Initialization?
A: We can possibly recover the data on these cases. It will depend on the RAID controller’s functionality and how much data was copied to array. Contact us to know how we can help you in your RAID data recovery process.
(rād) Short for Redundant Array of Independent (or Inexpensive) Disks, a category of disk drives that employ two or more drives in combination for fault tolerance and performance.
There are number of different RAID levels:
RAID Level 0 -- Striped Disk Array without Fault Tolerance: Provides data striping (spreading out blocks of each file across multiple disk drives) but no redundancy. This improves performance but does not deliver fault tolerance. If one drive fails then all data in the array is lost.
RAID Level 1 -- Mirroring and Duplexing: Provides disk mirroring. Level 1 provides twice the read transaction rate of single disks and the same write transaction rate as single disks.
RAID Level 2 -- Error-Correcting Coding: Not a typical implementation and rarely used, Level 2 stripes data at the bit level rather than the block level.
RAID Level 3 -- Bit-Interleaved Parity: Provides byte-level striping with a dedicated parity disk. Level 3, which cannot service simultaneous multiple requests, also is rarely used.
RAID Level 4 -- Dedicated Parity Drive: A commonly used implementation of RAID, Level 4 provides block-level striping (like Level 0) with a parity disk. If a data disk fails, the parity data is used to create a replacement disk. A disadvantage to Level 4 is that the parity disk can create write bottlenecks.
RAID Level 5 -- Block Interleaved Distributed Parity: Provides data striping at the byte level and also stripe error correction information. This results in excellent performance and good fault tolerance. Level 5 is one of the most popular implementations of RAID.
RAID Level 6 -- Independent Data Disks with Double Parity: Provides block-level striping with parity data distributed across all disks.
RAID Level 0+1 – A Mirror of Stripes: Not one of the original RAID levels, two RAID 0 stripes are created, and a RAID 1 mirror is created over them. Used for both replicating and sharing data among disks.
RAID Level 10 – A Stripe of Mirrors: Not one of the original RAID levels, multiple RAID 1 mirrors are created, and a RAID 0 stripe is created over these.
RAID Level 7: A trademark of Storage Computer Corporation that adds caching to Levels 3 or 4.
RAID S: EMC Corporation's proprietary striped parity RAID system used in its Symmetrix storage systems.
