The high-performance 73 GB Ultra320 SCSI Hard Drive from Dell is ideal for Dell PowerEdge 1550/1650/1750 Servers. The drive features a 15,000 RPM spindle speed for fast performance and an Ultra320 SCSI interface for data transfer rates of up to 320 MBps and differential data integrity. It has a rotational speed of 15, 000 rpm and an average seek time of 3.6 ms, which provides faster disk access. The drive also supports Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) which alerts the system of any negative reliability status conditions. The host system can then alert and advise users on taking appropriate actions to avoid potential system failure or downtime. Just-In-Time (JIT) minimizes actuator impact on power, vibration and acoustics. It features SeaShell packaging which protects the device from external shock.
