Model Brand Western Digital Series RE2 Model WD7500AYYS Packaging Bare Drive Performance Interface SATA 3.0Gb/s Capacity 750GB RPM 7200 RPM Cache 16MB Average Seek Time 8.9ms Average Write Time 9.6ms Average Latency 4.2ms Features Features Superior reliability - Designed and manufactured to server-class standards to provide best-in-class enterprise reliability in high duty cycle environments. With 1.2 million hours MTBF, these drives have the highest available reliability rating on a high-capacity drive. Low power - Active Power Save delivers best-in-class seek mode power consumption through an advanced WD firmware which conserves power in active seek modes without degrading performance. RAID-specific, time-limited error recovery (TLER) - A feature pioneered by WD, significantly reduces drive fallout caused by the extended hard drive error-recovery processes common to desktop drives. Rotary Acceleration Feed Forward (RAFF) - Provides best-in-class vibration tolerance by optimizing operation and performance when the drives are used in vibration-prone, multidrive systems such as rack-mounted servers or network storage.
