Dell 400-AFTB 300GB SAS drive

The Dell 400-AFTB is a 300GB internal hard drive with a 2.5 inch form factor and a SAS 12Gb/s interface. It spins at 10000 RPM and is supplied as a bare drive with a hot-swap tray. The unit is designed for Dell servers and storage arrays that accept 2.5 inch SAS drives.

Who this suits and who should look elsewhere

This drive suits administrators replacing a failed Dell 400-AFTB part or expanding a compatible 2.5 inch SAS bay. It is not for systems that lack a SAS 12Gb/s backplane or that require a larger capacity than 300GB. Buyers needing a different interface or a non-hot-swap mechanical design should select another model.

The specification that decides fit

The SAS 12Gb/s interface combined with the 2.5 inch 10000 RPM form factor determines whether this drive will install and operate in the target chassis. Verify that the server or array lists part number 400-AFTB as a supported component before purchase.

Questions about this item

How can I confirm the Dell 400-AFTB is spinning at 10000 RPM and communicating over SAS 12Gb/s after installation?

The drive should be detected by the RAID controller or HBA at 12Gb/s link speed, and SMART data will report 10000 RPM rotational speed.

The listing says packaging is bare drive; does the 400-AFTB include a hot-swap tray or must I supply my own 2.5" carrier?

The unit is a bare drive without a tray; you need a compatible 2.5" hot-swap carrier for your Dell server or enclosure.

We need several 300GB 10K SAS drives — is the 400-AFTB the only Dell part number for this capacity and speed combination?

400-AFTB is the specific Dell part number for a 300GB 2.5" 10K SAS 12Gb/s drive; other part numbers indicate different capacities or speeds.
