Dell 400-ALIG 1.2TB SAS Drive

This Dell 400-ALIG is a 1.2TB internal hard drive built for servers and storage arrays that need fast mechanical storage. It uses a 2.5 inch form factor and spins at 10000 RPM for quick data access. The bare drive ships without a tray and is sold in new condition.

SAS 12Gb/s Interface Compatibility

The single specification that decides fit is the SAS interface running at 12Gb/s transfer rate. Your controller or backplane must support this exact interface speed to recognise the drive and achieve full throughput. A 3Gb/s or 6Gb/s only host will limit performance or prevent detection.

Sustained Load Behaviour

Under continuous workloads the 10000 RPM spindle maintains consistent throughput for sequential reads and writes. The mechanical design handles sustained I/O without the thermal throttling seen in solid-state alternatives. Hot-swap support allows replacement without powering down the enclosure.

Questions about this item

What does the 10000 RPM spindle speed mean for latency inside a server?

A 10000 RPM spindle yields roughly 3 ms average rotational latency, so read requests spend less time waiting for the platter to arrive under the head.

What does the 12Gb/s SAS interface actually cap in practice?

The drive uses a SAS 12Gb/s link, so the bus ceiling is 12 Gb/s; sustained throughput will be lower and depends on the controller and backplane.

What physical space and mounting does the 2.5" hot-swap tray need?

The drive fits a standard 2.5-inch hot-swap bay and uses the tray's connector for power and data; no separate cables are required.
