Software RAID can also provide data redundancy. Software RAID combines multiple drives into a logical volume through Disk Management feature provided by operating system. Besides, this RAID is only suitable for RAID 0 and RAID 1. This RAID will also provide fault-tolerance and improve performance. However, Hardware assisted RAID lacks special I/O processing chip, so it will occupy the resources of CPU. Hardware assisted RAID needs a RAID card and drivers provided by manufacturers. But generally speaking, hardware RAID is expensive and is usually applied in servers. These devices make hardware RAID have best performance. Besides, hardware RAID also includes special I/O processing chip and array buffer. The RAID controller on the card combines drives into a virtual volume. Hardware RAID uses a RAID card to connect drives with computer. RAID has three types: external disk array cabinet (so called hardware RAID), internal disk array card (so called hardware-assisted RAID), and software simulation (so called software RAID). It will also utilize the multiple drives to improve the performance of the drive array, including MTBF (Mean Time Between Failure) and fault-tolerance. RAID (Redundant Arrays of Independent Drives) technology combines multiple drives into a drive array with huge capacity.
