Dell 400-ALQT 2TB Nearline SAS Drive

This 2 TB 3.5-inch internal hard drive uses a Nearline SAS interface running at 12 Gb/s and spins at 7200 RPM. It is supplied as a bare drive with the original Dell part number 400-ALQT.

Suited for Dell PowerEdge and PowerVault arrays

The drive is qualified for a wide range of Dell PowerEdge rack and tower servers including the R210, R230, R310, R320, R330, R410, R420, R430, R510, R520, R530, R710, R720, R720XD, R730, R730XD, T110, T110 II, T310, T320, T330, T410, T420, T430, T610, T620, T630, T710 and VRTX. It is also compatible with PowerVault DL2200, DR4000, DR4100, DX6104 SN, DX6112 SN and MD1 storage arrays. Buyers who need a different interface or a non-Dell qualified drive should consider other options.

12 Gb/s SAS interface decides fit

The single specification that determines compatibility is the 12 Gb/s Nearline SAS interface; the system or backplane must support this exact standard for the drive to function correctly.

Questions about this item

How do I install the 400-ALQT into a PowerEdge R720 server and what step is often missed?

Slide the 3.5" drive into a hot-swap bay until the carrier clicks, then ensure the SAS connector seats fully; the step often missed is verifying the backplane negotiates 12Gb/s instead of falling back to 3Gb/s.

What maintenance will the 2TB Nearline SAS drive need over its service life?

No scheduled mechanical maintenance is required; monitor SMART reallocated-sector counts and replace the drive once the attribute approaches the vendor threshold.

What limit appears first when the 7200 RPM drive runs sustained writes?

The 12Gb/s SAS interface ceiling is reached before the mechanical media saturates, so sustained throughput tops out at the link rate.
