900 GB SAS enterprise drive

This Dell internal hard drive delivers 900 GB of storage on a 2.5 inch form factor. It spins at 10000 RPM and connects through a SAS 6Gb/s interface. The 512n sector format ensures compatibility with legacy enterprise arrays. It is built for continuous operation in storage servers and disk arrays.

Suited for high-throughput arrays

The drive fits administrators who need fast rotational speed and SAS connectivity for transactional workloads. It is not suited for systems that only accept 3.5 inch bays or lack a SAS controller. Buyers wanting larger capacity per spindle or lower power draw should consider other options. Desktop users without enterprise RAID hardware will not benefit from this drive.

10000 RPM spindle speed

The 10000 RPM rotation rate is the primary factor that determines random I/O performance and latency. This speed supports demanding database and virtualisation workloads that require quick seek times. Verify that your backplane and controller support 6Gb/s SAS before purchase. The 512n sector size must match the array configuration.

Questions about this item

Will the 2.5" 900GB SAS 6Gb/s drive work in a server that currently uses 3.5" SAS drives?

The 2.5" form factor requires a compatible drive bay or a 3.5" adapter bracket; the SAS 6Gb/s interface is electrically compatible with 6Gb/s and 12Gb/s backplanes.

How can I verify the 10000 RPM drive is running at the correct speed after installation?

Check the drive's reported RPM value in your RAID controller BIOS, iDRAC, or operating system disk utility; it should read 10000 RPM.

Does the 512n Dell 900GB SAS drive ship with a mounting bracket or caddy?

The drive is supplied as a bare unit; a Dell 2.5" hot-plug caddy or bracket for your specific server model must be purchased separately.
