Dell 300GB SAS 12Gb/s 10K Drive

This Dell 400-AKHM is a 300GB 2.5" internal hard drive with a SAS 12Gb/s interface spinning at 10000 RPM. It arrives as a bare drive with hot-swap capability for compatible bays. The 12Gb/s transfer rate supports high-throughput workloads in Dell servers and arrays.

Suits Dell systems needing 10K SAS storage

This drive fits Dell servers and storage arrays that accept 2.5" hot-swap SAS drives at 12Gb/s. It is not for systems limited to 3.5" bays or 6Gb/s backplanes. Buyers needing larger capacity or solid-state speed should look elsewhere.

12Gb/s SAS interface decides compatibility

The single specification that determines fit is the 12Gb/s SAS interface. Your backplane and controller must support this exact signalling rate and protocol. Without 12Gb/s SAS support the drive will not function.

Questions about this item

How do I install the 2.5" SAS drive in a hot-swap bay and what step is often missed?

Slide the drive into the hot-swap tray until the SAS connector seats firmly, then lock the release lever; the step often missed is not pushing far enough for the 12Gb/s link to negotiate.

What maintenance or replacement will the 10000 RPM drive need later?

Mechanical bearings and spindle motor wear over time; plan to replace the 300GB unit when SMART reallocated-sector counts rise or seek errors appear.

What limit appears first on the 12Gb/s SAS interface during sustained writes?

The 10000 RPM rotational latency and media transfer rate saturate before the 12Gb/s bus, so sustained throughput plateaus at the drive's physical write speed.
