Enterprise 2.5" SAS drive

The Seagate ST9300605SS is a 300 GB 2.5 inch internal hard drive spinning at 10000 RPM with a 6 Gb/s SAS interface and 64 MB cache. It is built for servers and storage arrays that require a small-form-factor drive with enterprise-grade rotational speed.

Suits RAID and tiered storage

This drive fits administrators who need consistent 10K RPM throughput for database logs, transactional workloads or high-performance RAID volumes. It is not suited for desktop PCs lacking a SAS controller, nor for users who want larger capacities or the lower power draw of solid-state media.

300 GB with 64 MB buffer

The 300 GB capacity handles operating-system volumes, application binaries and active data sets that benefit from low-latency mechanical access. The 64 MB cache absorbs burst writes, but sustained sequential transfers will saturate the 6 Gb/s link before the buffer can compensate, and the drive cannot scale beyond its fixed 300 GB limit.

Questions about this item

Does my server or workstation need a SAS 6Gb/s backplane or controller to use the ST9300605SS?

Yes, the drive uses a 2.5" SAS 6Gb/s interface, so the host must provide a compatible SAS connector and controller.

Can the ST9300605SS share a SAS backplane with older 3Gb/s SAS drives?

The drive supports the SAS 6Gb/s standard; it will negotiate link speed with the controller and coexist with slower SAS devices on the same bus.

How can I confirm the drive is running at 10000RPM with its 64MB cache after installation?

Check the drive’s reported rotational speed and cache size in the RAID controller BIOS or with a tool such as smartctl that queries the drive’s identity page.
