DESC: Simply the best price/performance, lowest cost of ownership disc drive ever. The Cheetah 15K.4 is the highest-performance drive ever offered by Seagate, delivering maximum IOPS with fewer drives to yield lower TCO. The Cheetah 15K.4 price-per-performance value united with the breakthrough benefits of serial attached SCSI (SAS) make it the optimal 3.5-inch drive for rock solid enterprise storage. Proactive, self-initiated background management functions improve media integrity, increase drive efficiency, reduce incidence of integration failures and improve field reliability. The Cheetah 15K.4 shares its electronics architecture and firmware base with Cheetah 10K.7 and Savvio to ensure greater factory consistency and reduced time to market.
