• Resumen

  • For end users, the five most externally visible characteristics of a disk drive are capacity, price, interface type (e.g. SCSI, ATA, Fibre Channel, SATA), performance (e.g. access time, I/Os per second, sustained transfer rate) and reliability (e.g. MTBF or unrecoverable read error rate).

    When evaluating a drive for a particular application, these attributes carry varying weight. We'll examine how these attibutes are related in real disk drive implementations, what applications are best suited to specific drive types, and what the future holds for disk storage in the enterprise.
