Dell 31N08 1TB 2.5" SATA 7200 RPM

This is a new 1TB internal hard drive from Dell, part number 31N08. It uses a 2.5-inch form factor with a SATA interface spinning at 7200 RPM. The drive is supplied as a bare unit without retail packaging.

Suited for server storage upgrades

The drive is intended for server environments that accept 2.5-inch SATA drives. It is not for systems that require a 3.5-inch form factor or a different physical interface. Buyers needing a larger capacity or a non-SATA connection should consider other options.

7200 RPM spindle speed

The 7200 RPM rotation rate determines the drive's sustained throughput and access latency. This specification is the primary factor when matching the drive to a server workload that expects 7.2K performance.

Questions about this item

Will the 2.5" form factor fit my server's hot-swap tray without an adapter?

The drive is a 2.5" SATA unit built for hot-swap bays that accept the standard 7.2K 6Gb/s interface; verify your tray matches the 2.5" form factor before ordering.

Which orientation and screw pattern should I use when mounting the drive in a hot-swap carrier?

Align the drive with the carrier's SATA connector facing the backplane, then secure it using the four bottom mounting holes on the 2.5" chassis.

How often should I run a surface scan on this 7200 RPM drive in a server?

Schedule a full surface scan at least once per quarter to catch early sector errors on the 1TB platters.
