The Dell 146.8 GB Hard Drive is an ideal data storage solution for your Dell PowerEdge Server. It has an 8 MB buffer and conforms to Ultra320 SCSI interface - providing maximum transfer rate 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. It 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. This product has been tested and validated on Dell systems to ensure it will work with your computer.
