||Rebuild of Raid array using incorrect disk elements or wrong sequence, resulting in irreversible lost of data
||Windows built in utility tor repair file system corruption. Not advisable to use as it will perform write on disk and result in data lost
||During disk failures, due to built-in tolerance of RAID configuration, data volume is still accessible but may be running at slower performance
||Store identical data accross disks
||Set of data blocks are computed to give a checksum called parity so in case any data block is missing, the value of the missing data block can be recomputed from the checksum together with the remaining data blocks
||PCI or PCI Express card (could be integrated to montherboard) to provide a level of abstration layer between operating systems and physical drives which are then presented as logical units for which data protection or performance or capacity can be defined.
||A process to bring back the RAID servers back to its healthy condition by replacing the faulty disk and regenerating data/parity back to the new disk
||Split the data into certain size and then written to the individual disks in turn.
