| Q: How does the performance of SATA in RAID compare to SCSI in RAID?
Keep in mind that from a performance standpoint you may be comparing apples to oranges with SATA vs. parallel SCSI, as well as different adapters. Also, some ROCs or adapters are tuned for high-throughput reads or writes, while others may be tuned for lots of small I/O operations. For performance numbers, check out the Web sites of AMD, Applied Micro Circuits, Atto Technology, Intel and LSI, among others.
