300 GB SAS enterprise drive

The HP 507127-B21 is a 2.5-inch SFF hard drive built for 24/7 server workloads. It spins at 10000 RPM and connects through a SAS 6Gb/s interface. The 300 GB capacity suits transaction-heavy applications that demand consistent throughput.

Suited for high-IO server bays, not portable use

This drive targets administrators who need low-latency random access in hot-plug or fixed server chassis. It is not designed for laptop or desktop consumer workloads, nor for systems that lack a SAS backplane or controller.

10000 RPM spindle speed determines fit

The 10000 RPM rotational speed delivers the short 4 ms average seek time required by high-transaction databases. Buyers who need larger capacity per spindle or lower power draw should evaluate alternative drive classes.

Questions about this item

Does my server have a SAS 6Gb/s backplane for this 2.5" SFF drive?

The drive uses a SAS 6Gb/s interface in a 2.5" SFF form factor, so the server must provide a matching SAS backplane or controller with an available bay.

Can I mix this 10000 RPM SAS drive with slower midline drives in the same array?

Mixing 10000 RPM enterprise drives with slower midline drives in one array is not recommended because the array will run at the speed of the slowest member.

How do I confirm the drive runs at 10000 RPM after installation?

Check the drive information in the server BIOS or RAID controller utility; it should report 10000 RPM and a SAS 6Gb/s link speed.
