RAID Array data recovery
RAID arrays are typically found in different type of servers, or workstations that are used for data backup. Even some home desktops, large external drives, and laptops have RAID HDD setup in them. This setup allows you to connect 2 or more drives into one virtual unit, which spreads the data on all of the drives. There are different type of RAID arrays, and every one of them carries its own advantages and disadvantages, and by that, different difficulty of recovery
Popular RAID setups
- RAID 0 - used to boost the devices performance. Also known as "disk striping" in this array data is written across multiple disks, and this means that the work that the computer is doing is handled by multiple disks rather than just one, increasing performance. Minimum of two disks is required. This type of setup increases the performance at cost of error if one of these disks in the array fails. If that happens, the whole array fails and all data is jeopardized. Recovery is possible, but also depended on the damaged drive.
- RAID 1 - is a fault-tolerance configuration known as "disk mirroring." With this array data gets written simultaneously on both drives, and creates a mirror image of the 1st (or main) drive onto the second one. RAID 1 is kind of a backup option since it backs up all the work on one drive to another, in case one of the drive dies, the other one is fully accessible. It is very rare that both drives get damaged at the same time. Downside of RAID 1 is decrease in overall performance.
- RAID 5 - the most common RAID configuration for business servers and enterprise NAS devices. This level provides better performance than mirroring as well as fault tolerance. With RAID 5, data and parity (which is additional data used for recovery) are striped across three or more disks. If a disk gets an error or starts to fail, data is recreated from this distributed data and parity block automatically. The system is still operational even when one disk stops working until you can replace the failed drive.
- If you have an issue with your RAID array we can help you recover your data.
If you have an issue with your RAID array we can help you recover your data.
If we don’t recover it, you don’t pay for it! If we are unable to recover your data, we wont charge you a single dollar, because we strongly believe that it is not fair to charge a person for the data that wasn’t even recovered, comparing to a lot of other companies that actually do charge for something they didn’t do.
Always FREE estimates! We always offer a free quote before any job we do, so you have better understanding of a problem and how much it will cost you. Same rule applies to all our data recovery jobs.
