900 GB 2.5" SAS enterprise drive

This Dell 400-ACXT is a 900 GB 2.5 inch SAS hard drive spinning at 10000 RPM. It is built for servers and storage arrays that need fast sequential access and high IOPS in a compact form factor. The bare-drive packaging means it arrives without a carrier, ready for hot-swap trays.

Hot-swap tray compatibility

The drive uses a standard 2.5 inch SAS connector and is designed for hot-swap trays, allowing replacement without powering down the enclosure. A 12 Gb/s interface supports the 6 Gb/s transfer rate, so existing 6 Gb/s backplanes work without negotiation issues. Bare drive delivery requires the installer to supply a matching carrier or sled.

10K RPM thermal profile

At 10000 RPM the spindle generates more heat and vibration than slower drives, so adequate airflow in the drive bay is necessary for sustained operation. Power draw rises during heavy random workloads, and the acoustic profile is noticeable in quiet rack environments. The SAS interface maintains consistent throughput under load without protocol overhead.

Questions about this item

What practical throughput does the SAS 12Gb/s interface cap at with this drive?

The drive's transfer rate is 6Gb/s, so the SAS 12Gb/s link will operate at 6Gb/s in practice.

What physical space and mounting style does the 2.5-inch hot-swap tray require?

It fits a standard 2.5-inch hot-swap bay; the tray slides in and locks without screws.

How is the drive installed and which step is often missed?

Slide the hot-swap tray into the bay until the latch clicks; the step often missed is ensuring the latch fully engages to connect the SAS and power contacts.
