300GB SAS drive for servers

This 300GB IBM drive spins at 10000 RPM and uses a SAS interface. It is built for server environments that need reliable internal storage. The 2.5 inch form factor fits standard hot-swap bays. Buyers needing larger capacities should look elsewhere.

SAS 3Gb/s interface limits

The drive connects through a SAS 3Gb/s link, which caps the maximum bus throughput. Average latency is listed at 6Gb/s, but the interface itself cannot exceed 3Gb/s. Systems with faster SAS controllers will not see higher transfer rates from this unit. The interface also requires a compatible backplane or HBA.

Bare drive with hot-swap tray

Supplied as a bare drive, it is designed for hot-swap trays in server chassis. No mounting screws or cables are included in the package. The 2.5 inch size allows dense drive configurations in rack units. Retail or OEM packing may vary.

Questions about this item

Should I choose the 300 GB capacity or a different size for my server?

The 300 GB capacity suits transaction-heavy workloads where low latency matters more than raw space.

What does the 10 000 RPM spindle speed mean once the drive is installed?

The 10 000 RPM spindle reduces average rotational latency, so random I/O operations finish faster than on slower drives.

The SAS 3 Gb/s interface is listed — what does that cap in practice?

SAS 3 Gb/s limits the maximum sustained transfer rate to 3 Gb/s, even though the drive itself can signal at 6 Gb/s.
