A failed RAID array is one of the most stressful events a business can face. The good news: with the right engineers, most RAID failures are recoverable – including cases where the rebuild already failed, multiple drives are dead, or the controller is gone.
ACE RAID Recovery has recovered data from RAID arrays for over 40 years, with a 98% success rate. We work on RAID 0, 1, 5, 6, 10, 50 and 60 – from a two-disk mirror to a 28TB enterprise SAN – in our labs in Dallas, Houston, and Chicago, or securely remote via our ACE Remote Recovery Manager (ARRM).
Why RAID arrays fail
One or more disks die; with RAID 5, two active failures stop the array.
A rebuild that dies partway corrupts more data and kills the array. We see this in about 30% of RAID 5 cases that reach our lab.
The controller dies, and the array can’t be assembled without it.
Vendor firmware quietly corrupts metadata.
Arrays re-initialized, snapshots deleted, LUNs unmounted.
RAID levels we recover
| RAID level | Typical failure | Recovery |
|---|---|---|
| RAID 0 | One drive down = array dead | Possible from surviving drives |
| RAID 1 | Mirror broken, drive replaced | Possible from remaining disk |
| RAID 5 | Degraded, rebuild failed, second drive lost | Our most common recovery |
| RAID 6 | Two drives failed, double parity | Recovered in-lab |
| RAID 10 | Drives lost in both mirrored halves | Recovered in-lab |
| RAID 50 / 60 | Failures across nested groups | Complex – lab required |
Our recovery process
Free evaluation
An engineer assesses your array and tells you honestly if (and how) the data can be recovered.
Fixed quote
You approve a clear price before any work. Typical projects run $1,000-$2,500 per disk.
Recovery
In-lab or remote. We image every drive, rebuild the array virtually, and extract your data with proprietary tools.
Verification & return
You confirm your files; we deliver them on a new drive or via secure transfer.
Most recoveries take 3-15 days depending on complexity and data volume; emergency service runs 24-48 hours.
