Redundant array of independent disks (RAID)

nounid 3800·updated Aug 30, 2026
verified· unreviewed

The use of multiple hard disks to store the same data in different places. By placing data on multiple disks, I/O operations can overlap in a balanced way, improving performance. Since multiple disks increase the mean time between failures (MTBF), storing data redundantly also increases fault-tolerance.
