Dell 0T7F78 2TB Nearline SAS Drive

This Dell 0T7F78 is a 2TB 3.5 inch internal hard drive built for desktop and server storage. It uses a Nearline SAS interface rated at 12Gb/s and spins at 7200 RPM. The drive arrives as a bare unit without a tray or bracket. It suits users adding capacity to compatible SAS backplanes.

Who this suits and who it does not

This drive fits systems with a 3.5 inch bay and a SAS controller that supports 12Gb/s operation. It is not for platforms limited to 6Gb/s SAS links or those without a SAS host adapter. Buyers needing hot-swap trays must source them separately.

The deciding specification

The interface runs at 12Gb/s SAS while the media transfer rate is 6Gb/s. A controller limited to 6Gb/s will cap throughput to the lower figure. Verify your backplane and HBA generation before purchase.

Questions about this item

How do I install the Dell 0T7F78 2TB SAS drive and which step is often missed?

Mount the 3.5" drive in a SAS bay, connect the SAS data and power cables, then configure the controller to recognise the 12Gb/s link; the step often missed is enabling the correct SAS link speed in the RAID or HBA BIOS.

What maintenance or replacement will the Dell 0T7F78 2TB 7200 RPM drive need later?

As a mechanical nearline SAS HDD, it has no user-serviceable parts; plan to replace the entire drive once SMART attributes indicate wear or after the rated workload limit is reached.

What limit appears first on the Dell 0T7F78 2TB SAS drive during sustained writes?

The 6Gb/s transfer rate of the nearline SAS interface caps sustained throughput before the 7200 RPM platters reach their maximum media speed.
