Small silver 2.5 inch SAS hard drive with hot-plug tray

DELL

DELL 400-AUWU 1.2 TB 10K SAS 12Gbps 2.5" hot-plug hard drive

SKU CH-ASH8-7B84X

A 1.2 TB SAS hard drive spinning at 10000 rpm with a 12Gbps interface in a hot-pluggable 2.5 inch form factor

  • 2 TB capacity stores large amounts of data
  • 10,000 RPM spindle speed ensures fast disk access
  • SAS 12Gbps interface delivers high data transfer speeds
  • 5 inch hot-plug form factor allows drive replacement without shutdown
  • 512n sector format supports broad system compatibility

1.2 TB 10K SAS drive for 14G servers

The Dell 400-AUWU is a 1.2 TB 10,000 RPM SAS hard drive built for 14G PowerEdge servers. It targets administrators who need fast disk access for transactional workloads and databases. The 12Gb/s SAS interface supports high data transfer speeds within compatible arrays. Hot-plug capability allows drive replacement without powering down the host.

2.5-inch hot-plug bay with 12Gb/s SAS backplane

This 2.5-inch drive slides into a hot-swap bay wired for 12Gb/s SAS. A matching backplane and RAID controller are required to operate at the rated interface speed. The 512n sector format ensures compatibility with legacy operating systems and hypervisors. No additional cabling is needed beyond the standard backplane connection.

Sustained 10K RPM throughput under continuous load

The 10,000 RPM spindle maintains consistent throughput during extended read and write operations rather than only in short bursts. Mechanical latency remains predictable for OLTP and logging workloads that run around the clock. The SAS protocol provides dual-port redundancy for path failover during heavy I/O. Thermal output stays within the chassis limits defined for 14G platforms.

Questions about this item

Does the 10 000 RPM spindle speed create a thermal limit under sustained use?

The 10 000 RPM spindle speed is the rated operating speed; sustained workloads run at this speed within the drive's design envelope.

How much heat or noise does the 1.2 TB SAS drive produce when running all day?

The 1.2 TB SAS drive operates at its specified 10 000 RPM spindle speed continuously; acoustic and thermal output remain within normal enterprise drive parameters.

Must the server already have a 12Gb/s SAS backplane for this 2.5" hot-plug drive to work?

Yes, the drive requires a 12Gb/s SAS interface and a 2.5" hot-plug bay; it will not function without both.
