Dell U738K 1TB SAS drive

The Dell U738K is a 1TB 3.5" internal hard drive with a SAS 6Gb/s interface spinning at 7200 RPM. It uses SLC NAND flash memory and ships as a bare drive in original Dell packaging. This component is built for desktop and server storage bays.

Suits servers needing SAS 7.2K storage

This drive fits systems that require a SAS 6Gb/s connection and a 3.5" form factor. It is not for builds limited to other interfaces or smaller drive bays. Buyers needing higher capacity or different physical dimensions should consider alternative drives.

SAS 6Gb/s interface decides compatibility

The single specification that determines fit is the SAS 6Gb/s interface. Your controller or backplane must support this exact protocol for the drive to function. Verify the host connector type before purchase.
