Dell 1.2TB SAS 10K Drive

This Dell 400-AUTI is a new 1.2TB internal hard drive with a 2.5 inch form factor. It uses a SAS interface running at 12Gb/s and spins at 10000 RPM. The drive is supplied as a bare unit with hot-swap capability for compatible bays.

Server storage upgrade fit

It suits administrators adding fast nearline storage to Dell PowerEdge servers or external arrays that accept 2.5 inch SAS drives. The 10K spindle speed supports transactional workloads and mixed read-write patterns. Buyers who need larger capacity per drive bay or a different physical interface should look at other parts.

SAS 12Gb/s interface check

The single specification that decides fit is the SAS 12Gb/s interface. Your controller or backplane must support this exact protocol and speed for the drive to operate. Verify the system documentation lists SAS 12Gb/s compatibility before purchase.

Questions about this item

How can I confirm the 1.2TB SAS drive is running at 10000 RPM after installation?

Check the drive’s reported rotational speed in your RAID controller BIOS or OS disk utility; it should show 10000 RPM for this model.

The listing says Packaging: Bare Drive — does the 400-AUTI ship with a hot-swap tray or must I supply one?

The drive is supplied as a bare unit; a compatible Dell hot-swap tray or caddy for 2.5" SAS bays must be purchased separately.

I see only the 1.2TB capacity listed for the 400-AUTI — are other capacities sold under this same part number?

Part number 400-AUTI identifies the 1.2TB 10K SAS model specifically; different capacities carry their own Dell part numbers.
