Compare SATA with SCSI – a point in favor of SCSI

We compared SATA against SCSI previously, but here is another point to consider in favor of SCSI: SCSI is considered faster than SATA because SCSI has processor onboard that is specialized to handle disk read operations, SATA does not. The major reason for choosing/paying for SCSI/SAS over SATA, is not speed, but reliability. A SATA/PATA [...]

Serial Attached SCSI (SAS)

SAS is serial attached SCSI. SAS takes SATA2 (3.0Gbit/s wire speed) Point To Point protocol while the SCSI drives just allow for a shared bus. SAS allows for much higher speed data transfers than IDE or SCSI, but is still backwards-compatible with SATA drives. Reference Wikipedia

Compare SATA vs SCSI

SATA’s architecture wins hand-down over bus architectures such as SCSI. SATA provides a unique cable for connectivity to each drive. Plus, you can live with a cable failure in a SATA array by using a suitable RAID. The same is not true with a multi-target bus. Source TigerDirect So it would seem that SATA plus [...]

SCSI for Fast Disk Access

Small Computer System Interface (SCSI) is a set of standards for physically connecting and transferring data between computers and peripheral devices. Reference Wikipedia SCSI interfaces provide for faster data transmission rates (up to 80 megabytes per second) than standard serial and parallel ports. In addition, you can attach many devices to a single SCSI port, [...]
