The OS driver only sees RAID arrays, and uses RAID-specific commands to read/write data. These controllers are what I call true hardware RAID. * Sometimes the term refers to controllers where the OS driver and card's on-board flash BIOS provide 100 percent of the RAID capability. This is called software RAID, or less flatteringly, fake RAID. * Occasionally, the term refers to controllers that have special features designed to enhance RAID, but still the OS driver must use normal ATA or SCSI commands to talk to the underlying disk devices. I classify these unique controllers as RAID accelerators, as they fall somewhere in between hardware RAID and software RAID.
