Dell 400-ALBN 1.2TB SAS drive

This Dell 400-ALBN is a 1.2TB internal hard drive built for servers and storage arrays that need fast, reliable access. It suits administrators who want consistent throughput for databases or virtualisation workloads. The 10000 RPM spindle and SAS 12Gb/s interface deliver the sustained performance those tasks demand.

Hot-swap 2.5-inch bare drive

The 2.5-inch form factor fits dense drive bays and the hot-swap tray lets you replace a unit without powering down the chassis. Bare-drive packaging means no retail box or cables are included, so plan for tray compatibility and cabling in your enclosure. This design supports quick maintenance in production environments.

SAS 12Gb/s interface limits

The SAS 12Gb/s link caps theoretical bandwidth at 12Gb/s, so overall throughput cannot exceed that ceiling. Mechanical latency at 10000 RPM remains higher than solid-state alternatives, affecting random I/O heavy workloads. Buyers needing lower latency or higher IOPS should consider flash-based media instead.

Questions about this item

Does the SAS 12Gb/s interface limit real-world throughput on this drive?

The 12Gb/s SAS link is the theoretical ceiling; sustained rates are lower and depend on the 10000 RPM spindle speed and controller capabilities.

What physical space and mounting does the 2.5-inch form factor require?

It fits a standard 2.5-inch drive bay and uses a hot-swap tray for tool-less insertion into compatible Dell servers or enclosures.

How is the hot-swap tray installed and what step is often missed?

Slide the bare drive into the tray until the connector seats firmly, then lock the latch; the common miss is not fully engaging the latch before powering on.
