A 300 GB 2.5-inch SAS hard drive spinning at 15 000 RPM with a 12 Gb/s interface and hot-swap tray
The Dell 400-AVVV is a 300GB 2.5 inch SAS hard drive spinning at 15000 RPM with a 12Gb/s interface. It is built for servers and storage arrays that need fast, reliable access to transactional data. The hot-swap tray allows replacement without powering down the chassis. This drive suits administrators who prioritise consistent throughput over maximum capacity.
At 15000 RPM the spindle generates measurable heat and audible whine typical of enterprise 2.5 inch SAS drives. Power draw sits above slower nearline disks but remains within the envelope for standard drive bays. System fans usually mask the acoustic signature in a rack environment. No specific thermal or acoustic figures are published by the manufacturer.
The 15000 RPM spindle maintains steady random IOPS during prolonged database or virtualisation workloads. SAS 12Gb/s bandwidth prevents the interface from becoming the bottleneck during sequential transfers. Write latency stays predictable because the drive lacks the garbage-collection pauses seen in flash media. Workloads needing larger sequential throughput or silent operation should consider alternative media.

Slide the drive into the hot-swap tray until the SAS connector seats firmly, then lock the lever; the step often missed is fully engaging the lever so the 12Gb/s link trains at 15000 RPM.
As a 15000 RPM mechanical drive, it will eventually need replacement when bearing wear or media errors appear; no user-serviceable parts exist, so plan a spare 300GB SAS unit.
The 12Gb/s SAS interface and 15000 RPM spindle set the sustained throughput ceiling; thermal throttling or write latency spikes typically hit before the 300GB capacity fills.
