RAID stands for Redundant Array of Inexpensive Disks.The main purpose of raid is to increase logical capacity of storage devices used,improve read/write performance and ensure redundancy in case of a hard disk failure. Raid devices are marked by two letters and a number. Eg. md0,md1,md2. Raid is mostly used in large file servers where data accessibility is higher. Raid unit appears to be equivalent to a single large capacity disk drive. The remarkable benefit of disk array is that if any single disk in the RAID fails, the system and array still continues to function without …
