SAS 10K enterprise drive

This 2.5-inch SAS hard drive delivers 1.2 TB of storage at 10000 RPM with a 128 MB cache. It is built for hot-swap bays in Dell 14th-generation PowerEdge servers such as the R440, R540, R6415, R7415 and R7425. The drive suits IT teams that need fast, reliable nearline capacity for database, virtualization or logging workloads in a validated server chassis.

Fit for validated PowerEdge bays

The drive fits the listed PowerEdge models and other 2.5-inch SAS hot-swap trays that accept 10K enterprise drives. It is not suited for desktop PCs, laptops or external enclosures that lack SAS backplanes or hot-swap carriers. Buyers who need larger capacities, solid-state speeds or SATA-only connectivity should consider different media.

12 Gb/s SAS interface

The single specification that decides compatibility is the SAS interface running at 12 Gb/s, which requires a matching SAS controller or backplane. Without a SAS host connection the drive will not function, so verify your server or HBA supports SAS before purchasing.

Questions about this item

What sustained-load limit appears first on a 10000 RPM SAS drive with 128MB cache?

The 10000 RPM spindle speed and 128MB cache define the mechanical and buffer limits that constrain sustained throughput under continuous workloads.

How much noise, heat or power does a 1.2TB 10000 RPM SAS drive produce when running all day?

A 1.2TB 10000 RPM SAS drive generates typical enterprise-level heat and acoustic output for its speed class; power draw scales with the 10000 RPM spindle and SAS interface activity.

What must my system already have to use a hot-swap 2.5" SAS drive?

A 2.5" hot-swap SAS backplane or cage with a compatible SAS controller or RAID card is required for the drive to function.
