At WeRecoverData.com®, we pride ourselves on our expertise in RAID Data Recovery, which stands as a cornerstone among the comprehensive data recovery services we provide. RAID systems offer significant advantages in terms of data speed and accessibility, ensuring a higher level of data protection compared to non-RAID disk configurations. However, the intricacies of disk management and data distribution across these systems can be quite challenging. (Discover more about RAID)
RAID Data Recovery
We re-striped/re-initialized the RAID array, formatted the array and copied data back to it. Is there a chance of recovering the data from before the array was re-striped/re-initialized?
It’s still possible to recover the data on these cases. It will depend on the RAID controller’s functionality and how much data was copied to the array. Contact us to determine how we can help you in your RAID data recovery process.
2 drives went down and are not recognized by the system in our RAID 5 system, can you still recover them?
It’s still possible to recover the data on these cases. We will have to create clones of the original drives with our equipment after disassembling the drives in the clean room. Then with the clones, we will rebuild the RAID array using our proprietary procedure. Please send us all drives that were used in the RAID system, we will need all of them to recover the data.
There are a number of different RAID levels:
Standard RAID Level
RAID Level 0
Striped Disk Array without Fault Tolerance: Provides data striping (spreading out blocks of each file across multiple disk drives) without 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 mirror 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.
Nested RAID Levels
That configuration provides redundancy and is typically combined with RAID 0 to achieve better read/write performance.
RAID 1 + 0
RAID 100 (RAID 1+0+0)
RAID 0+3 and 3+0
RAID 50 (RAID 5+0)
RAID 05 (RAID 0+5)
RAID 60 (RAID 6+0)
Non-Standard RAID Structure
EMC Corporation’s proprietary striped parity RAID system is used in its Symmetrix storage systems.
RAID 5E, RAID 5EE and RAID 6E
Intel Rapid Storage Technology (formerly called Intel Matrix RAID)
Linux MD RAID 10
Tahoe Distributed File System
We practically support any type of RAID-level format due to our capabilities.
