This 18.4 GB hard drive is an ideal storage solution for your Dell system. The drive features 15,000 RPM speed and Ultra320 SCSI interface with data transfer rates of up to 320 MBps. The flexibility and expandability of its SCSI interface allows users to construct a high performance reliable disk subsystem with a large storage capacity. Its advanced technology minimizes actuator impact on power, vibration and acoustics. 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. Additionally, its advanced design keeps performance on track by reducing the impact of rotational vibration in multi-drive environments.
