Increase the storage capacity of your system with this high-performance 146 GB Internal Hard Drive from Dell. With a high spindle speed of up to 10,000 RPM and 8 MB cache, the drive enables faster disk access. The flexibility and expandability of its Ultra320 SCSI interface allows you to construct a high performance and reliable disk subsystem, while providing data transfer rates up to 320 MBps. This internal hard 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.
