DataTech Labs ® provides fast, professional RAID 0 data recovery services. Our expert recovery engineers will work around the clock to ensure that your critical data is retrieved as quickly as possible. We understand that each customer’s situation is unique, so we will analyze each hard drive in your RAID 0 array to determine the best recovery method for each of our clients.
A RAID 0 requires a minimum of two hard disks. Data is striped between the disks in increments of either 64 or 128 KB (normally). This configuration offers no protection against data loss, since there is no parity information for redundancy. The RAID 0 setup does, however, offer increased performance. Because of multiple drives reading a single file at the same time, read performance from the array is higher. There is less of a difference on write time, and performance ratio decreases as the number of drives in the array increases.

What is RAID 0?
A RAID 0 array is a set of drives (minimum of 2) where data is stored in a series of stripes. Striping is where fragments of the aggregated data are written sequentially across each disk in the set. The fragments of data are then simultaneously written and read from the set of disks but treated as a unified system. Because fragments of data can be retrieved from multiple disks simultaneously, a set of RAID 0 drives have a higher performance rate and more access to usable storage compared to a single disk drive.
However, RAID 0 arrays are without parity, or redundancy. This means that the fragments of data stored on each disk are only on that specific disk and not repeated anywhere else in the array. When one sector on one of the disks fails, however, the corresponding sector on every other disk is rendered useless because part of the data is now corrupted.
Simply said, if one drive fails, all the data is unreadable and needs professional help.
For this reason, RAID 0 has been referred to as the “unrecoverable array type.” The more disks in the array, the more likely a disk could fail which leads to a higher risk of data loss. This “no fault tolerance,” can be devastating should a disk in your array become damaged or fail. With a RAID 0, always make sure you have a separate backup system that keeps a copy of your entire set of data in case of disk failure.
Some typical scenarios that cause RAID 0 data loss include:
- Hard Drive Failure
- Controller Failure
- Hardware trouble or failure
- Virus and File Corruption
- Formatting or Deleting Files
What to do when a RAID 0 Fails.
For any drive failure, it is important to act quickly to minimize the chances of permanent data loss. Immediately shut down the RAID and do not attempt to restore or rebuild it.
Although there are commercial data recovery software, using these programs can reduce chance of successful full recovery due by overwriting over damaged data. Similar, if there is internal damage to your drive, running these commercial software programs can cause further damage and lead to permanent file loss. For best chance of recovery, keep the RAID 0 shut down and call DataTech Labs ® for professional assistance.
