This is a hot-swap drive for HP servers using SAS / SATA controllers; It is recognized by HP SmartStart and has features like automatic firmware upgrade using HP utilities; It has special firmware to work with HP array controllers

Aside from firmware and testing this is no differnt than any other enterprise class SATA drive; It is not made by HP - they just test and change the firmware

received on time and work perfectly. would purchase again

These drives are hard to come by and I was glad to see them here on Buy.com. The drive works well with the DL120 Large form factor and the ML150/350 Large form factor. The drive is not as fast as the SAS HP drives but they do the job for a backup server.
