Bit interleaved parity raid
WebBit Interleaved Parity (Raid Level 3) Unlike the previous method, this uses a single parity disk to recover information instead of multiple parity disks. Consequently, each read and write accesses all the data disks, so only one operation can occur at a time. Thus, applications of this can be used in fields that require high bandwidth, but low ... Web• RAID-3 — similar to RAID-2, but uses a single check disk per group that contains the bit parity of the data disks; data is interleaved across all disks. Because disk reads are performed across the entire array and all data is transferred to the controller in parallel, RAID-3 is well suited for applications that require high data read ...

WebThe basic configurations of RAID are: LEVEL 0 : Striped set without parity/Non-Redundant Array. LEVEL 1 : Mirrored set without parity. LEVEL 2 : Redundancy through Hamming code. LEVEL 3 : Striped set with dedicated parity/Bit interleaved parity. LEVEL 4 : Block level parity. LEVEL 5 : Striped set with distributed parity.
