Designed to effectively address your data-intensive needs, the 160 GB Internal Hard Drive from Dell offers an ideal storage solution for your Dell Precision WorkStation. Featuring Serial ATA interface, this drive delivers data transfer rates of up to 150 MBps. It supports spindle speeds of up to 7200 RPM and includes an 8 MB buffer - ensuring faster data access. This 1-inch high internal hard drive incorporates an on-board Serial ATA interface controller. High capacity is achieved by a balanced combination of high areal recording density and the latest data encoding and servo techniques. 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.
