SAS 2 TB 7200 RPM drive

The Dell T7F78 is a 3.5-inch internal hard drive with a 2 TB capacity and a SAS interface. It spins at 7200 RPM and uses SLC NAND flash memory. The drive is supplied new in retail or OEM packaging.

Enterprise storage builds and RAID arrays

This drive suits servers and workstations that require a SAS connection for dual-port redundancy and consistent throughput. Builders whose motherboards or controllers lack a SAS port cannot install it. Buyers needing higher capacities or solid-state speeds should consider other options.

SAS interface compatibility

The single specification that decides fitment is the SAS interface. The system must provide a compatible SAS backplane or controller with the correct cabling and power connectors. Without native SAS support the drive will not function.
