SATA pros and cons The need for inexpensive, high-capacity storage media is growing. SATA hard disk drives are quickly becoming alternatives to higher cost Fibre Channel (FC) and SCSI drives for enterprises grappling with new compliance requirements and considering tiered storage strategies. SATA has evolved significantly from parallel ATA, but there are a number of issues that must be resolved before the drives can reliably support enterprise applications. SATA drives deliver storage capacities equivalent to FC/SCSI drives, but for as little as a quarter of the price per gigabyte. SATA drives are also available with much larger capacities than FC or SCSI disks. The major question is whether SATA drives can satisfy enterprise-class availability, data integrity and performance requirements. Parallel ATA SATA evolved from the parallel ATA interface, which has been used mainly in desktop and entry-level server systems. However, the performance and reliability characteristics of ATA drives were simply not engineered for enterprise storage. The initial serial ... Access >>>
