Western Digital has addressed the shortcomings of its previous models with the addition of a 16 MB buffer, NCQ, and native SATA implementation wrapped in two different packages depending upon your tastes and budget. With the upcoming transition from the parallel SCSI Ultra320 interface to the new Serial Attached SCSI interface, the drive stands a very good chance at competing successfully in the entry-level enterprise market. The SAS standard offers interoperability with the current SATA standards. In fact, both standards utilize the same physical connectors, while SAS host adapters can control SATA drives. This also offers the opportunity for the drive to become a standard in the workstation market where, historically, SCSI has competed well against SATA based upon performance to price ratios.
