RAID Failures Explained

The theory behind the error correction in RAID assumes that failures of drives are independent. In practice, the drives are often the same age, with similar wear. Many RAID failures are due to mechanical issues which are more likely on older drives, so the chances of a second drive failure after the first, are higher than thought. Where two drives fail, this will result in data loss. Most hard drives have a quoted service life of five years. However, users should be aware that drives are built to different levels of robustness, depending on their intended application. Enterprise-class fibre-channel and SAS drives are generally designed to withstand the heavy use in an array, but desktop-class drives are far less robust and being used in an array could shorten their life significantly. While RAID may protect against drive failure, the data is still exposed to operator, software, hardware and virus destruction.

Although RAID recovery is one of the most technically challenging types of data recovery, we are able to provide unmatched resources to make sure we can cover all the mainstream Raid levels. We also support proprietary RAID systems and have extensive experience with MAC, UNIX, FAT and VMware Raids.
