Purpose-built enterprise drive

The Dell 400-AUWU is a 1.2TB SAS 12Gb/s hard drive spinning at 10000 RPM in a 2.5-inch form factor. It targets servers and storage arrays that demand consistent throughput and low latency for transactional workloads. The SAS interface provides dual-port reliability for redundant controller paths.

SAS interface and spindle speed

The 12Gb/s SAS link removes the bottlenecks common on older 6Gb/s backplanes, letting the 10000 RPM platters sustain high sequential and random I/O. Dual-port connectivity enables multipath I/O and automatic failover without extra cabling. No software bundle or mounting hardware is included in the supplier data.

Capacity and workload fit

At 1.2TB the drive holds substantial databases, virtual machine images or logging archives while the 10000 RPM spindle keeps response times tight. It suits read-heavy and mixed OLTP workloads where capacity per spindle matters more than raw IOPS. Write-intensive or capacity-hungry environments will exhaust usable space or endurance before faster flash alternatives.
