Dell 401-AASQ 1.2TB SAS drive

This Dell 401-AASQ is a 1.2TB SAS hard drive built for servers and storage arrays that need fast, reliable data access. Its 10000 RPM spindle speed and 12Gb/s interface suit database workloads, virtualisation hosts and transaction-heavy applications. The 2.5 inch form factor fits dense drive bays and hot-swap trays. It is not for buyers who need larger capacities or solid-state latency.

Thermals noise and power in normal use

The 10000 RPM mechanism generates measurable heat and audible seek noise under sustained load, so adequate chassis airflow is required. Power draw rises during heavy random I/O, reflecting the mechanical design and 12Gb/s SAS signalling. Acoustic output is typical for enterprise 10K drives in multi-drive enclosures. No solid-state silence or low-power idle states are provided.

Hot-swap tray and bare-drive delivery

The drive ships as a bare unit with a hot-swap tray type that enables tool-less insertion and removal in compatible Dell bays. This tray lets administrators replace a failed disk without powering down the array, reducing downtime. No mounting screws, cables or management software are included in the package. Installers must supply any required backplane or caddy hardware separately.

Questions about this item

How do I install the Dell 401-AASQ 2.5" SAS drive into 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 tray lever; the step often missed is not pushing far enough for the 12Gb/s SAS interface to click into the backplane.

What maintenance or replacement will the Dell 401-AASQ 1.2TB 10000 RPM drive need over its service life?

As a mechanical 10000 RPM SAS hard drive, it will eventually need replacement when bearing wear or media errors appear; no user-serviceable parts exist, so plan a swap when SMART alerts or performance drops occur.

What limit appears first on the Dell 401-AASQ 12Gb/s SAS drive during sustained heavy writes?

The 10000 RPM mechanical latency and 12Gb/s SAS bus saturation become the bottleneck before the 1.2TB capacity fills, capping sustained throughput under continuous write workloads.
