Seagate

Seagate ST3300657SS 300GB 15K RPM 6Gb/s SAS internal hard drive

SKU CH-5BW6-EZHRW

Three 3.5-inch SAS hard drives spinning at 15000 RPM with 300 GB capacity and 16 MB cache

  • 15000 RPM spindle speed for fast transactional workloads
  • 6 Gb/s SAS interface for high-throughput server connectivity
  • 300 GB capacity fits dense storage arrays
  • 16 MB cache buffers burst I/O operations
  • 5 inch form factor matches standard enterprise bays

Enterprise SAS drive trio

This listing provides three new Seagate Cheetah 15K.7 hard drives, each delivering 300GB of storage in a 3.5in form factor. They spin at 15000RPM and connect through a 6Gb/s SAS interface with a 16MB cache. The drives are suited for servers and storage arrays that require high-speed enterprise storage.

Suited for multi-drive SAS arrays

The pack suits administrators populating multiple bays in a SAS backplane or RAID enclosure where matched spindles simplify volume creation. Buyers needing only a single drive or a different capacity should consider other options. Systems without a SAS host adapter cannot use these drives.

15000RPM spindle speed

The 15000RPM rotational speed is the defining specification that determines whether this drive meets the performance envelope of the target workload. It governs the sustained transfer rate and average latency that enterprise applications will experience.

Questions about this item

Does the 3.5" SAS 6Gb/s interface need a compatible SAS controller or backplane to work?

Yes, the ST3300657SS uses a 3.5" SAS 6Gb/s interface and requires a SAS host bus adapter, RAID controller, or backplane that supports 6 Gb/s SAS signalling.

Will the 15000 RPM Cheetah 15K.7 drive operate on a 3 Gb/s SAS backplane alongside older SAS drives?

The 6 Gb/s SAS interface is backward compatible with 3 Gb/s SAS backplanes, so the drive will run at the lower link speed when installed with older SAS drives.

How can I verify the 16 MB buffer and 15000 RPM speed are recognised after installation?

Check the drive identification in your RAID controller BIOS, SAS topology utility, or OS disk tool (for example smartctl) — it should report model ST3300657SS, 300 GB capacity, 15000 RPM, and 16 MB cache.
