RAID (redundant array of independent disks) is both a performance enhancer for your personal computer as well as a data storage system or fault tolerance. RAID organizes your data according to various RAID levels, creating copies of higher level data so that it can be retrieved in even of hard drive malfunction. It relies on additional drives, along with your hard drive, to categorize files in such a way that your computer is able to function more efficiently. However, with the use of RAID, the storage capacity of your computer becomes limited as it takes up a bit of space. RAID offers more of an advantage to those who own small businesses although personal computers can also benefit from RAID levels 0 and 1.
RAID 5 is a secure level of RAID that requires more than two hard drives for storage and function unlike lower levels. It is the most commonly used level of RAID because even in the event of single drive failure, data is still safe as it is stored on more than one disk. This level of RAID is the most common for personal computer users who are serious about their data and storage as it requires additional hard drives. It requires a more specialized approach to repair because it is more prone to corruption after failure than other RAID levels.
For RAID to be recovered software can be purchased or the hard drives can be sent into a RAID data recovery company that will retrieve lost data for a fee. There are numerous options for data recovery services but only certain companies create specific retrieval plans for RAID 5 data. After choosing a recovery service, your hard drive(s) must be removed from your computer and shipped to one of their locations.

Many computer users who experience hard drive or disk malfunctions will attempt to fix the problem themselves at home through a variety of DIY techniques that can actually cause more damage to your disks. This is highly advised against for several reasons. Computer engineers who are employed by RAID data recovery companies repair drives and disks in a special room known as a cleanroom. The environment in these rooms is impeccably clean and the air contains far fewer particles than any normal room, ensuring that the disks are not exposed to damaging particles when they are repaired.
