Dell 1.2 TB SAS drive for servers

This 2.5-inch hard drive delivers 1.2 TB of storage over a SAS 12Gb/s interface. It spins at 10000 RPM for fast data access in Dell PowerEdge servers. The drive is built for enterprise workloads that demand consistent throughput.

Hot-plug tray fits R640 R740 R740XD R940 C6420

The kit includes a carrier that slides into the front drive bays of the listed Dell PowerEdge models. Installation is tool-less and supports hot-plug replacement while the system runs. Compatibility is limited to the specified server chassis; other systems will not accept the tray.

Sustained 10K RPM performance under load

The 10000 RPM spindle maintains steady read and write rates during extended operations. SAS 12Gb/s signalling keeps the bus saturated without the latency spikes seen on slower interfaces. The drive is designed for continuous duty in multi-drive arrays.

Questions about this item

How do I confirm the 1.2TB 10000 RPM SAS drive is recognised at 12Gb/s after installation?

Check the RAID controller BIOS or OS disk utility for the negotiated link speed of 12Gb/s and verify the reported capacity matches 1.2TB with 10000 RPM.

Does the 400-AUWU kit include the 2.5" drive caddy and screws, or must I buy them separately?

The kit ships with the drive and the Dell hot-plug caddy for R640, R740, R740XD, R940 and C6420; no extra brackets are required.

Which capacity or speed version of the 2.5" 12Gb/s SAS drive should I choose for a Dell R740?

Select the 1.2TB 10K model 400-AUWU; it is the capacity and RPM combination validated for the R740 and listed servers.
