Abstract
A RAID system is provided which can be implemented as a hardware RAID system while avoiding certain shortcomings of previous RAID systems. The RAID system makes it possible to avoid or reduce the number of buffers or processors and can take advantage of drive logic to achieve RAID functions or enhancements. RAID functionality can be provided in a manner to accommodate one or more ATA drive interfaces. To avoid drive replacement problems, host requests for drive serial numbers are responded to with a mirror serial number. In one embodiment, the read address is used to select which drive will perform a read operation.
