RAID 1
(redirected from RAID1)

     0.01 sec.
RAID 1
(Redundant Array of Independent Disks Mode 1) A popular disk subsystem that increases safety by writing the same data on two drives. Called "mirroring," RAID 1 does not increase performance. However, if one drive fails, the second drive is used, and the failed drive is manually replaced. After replacement, the RAID controller duplicates the contents of the working drive onto the new one. See RAID 10 and RAID.



Mirroring for Fault Tolerance Widely used, mirroring writes two drives at the same time so that data are duplicated. It provides the highest reliability, but doubles the number of drives needed.
