Silver 3.5 inch bare SAS hard drive, circuit board visible

Seagate

Seagate Cheetah 15K.7 ST3300657SS 300GB 15000RPM SAS 6Gb/s 3.5in internal hard drive

SKU CH-HGGW-GKCZ4

A 3.5in SAS hard drive spinning at 15000RPM with 300GB capacity and a 16MB buffer

  • 15000 RPM spindle speed enables fast transactional throughput
  • SAS 6Gb/s interface provides reliable enterprise connectivity
  • 16 MB cache buffers bursts for consistent I/O performance
  • 300 GB capacity fits dense 3.5-inch server bays
  • New condition bare drive ready for immediate deployment

Capacity and spindle speed

This is a 300GB 3.5in SAS hard drive spinning at 15000RPM with a 16MB cache. It is sold new as a bare drive in a lot of 10 units. The 6Gb/s SAS interface suits servers and storage arrays that require high sustained throughput.

Suitable workloads and limits

The drive fits enterprise environments needing quick random access for databases or transaction logs. Buyers who want larger capacities or solid-state latency should look elsewhere. Systems without a SAS backplane or HBA cannot use this drive.

Deciding specification

The 15000RPM spindle speed is the single figure that determines whether this drive meets the performance target. If the application needs that rotational speed, the 300GB capacity and 6Gb/s SAS interface complete the match.

Highlights

  • 15000 RPM spindle speed enables fast transactional throughput
  • SAS 6Gb/s interface provides reliable enterprise connectivity
  • 16 MB cache buffers bursts for consistent I/O performance
  • 300 GB capacity fits dense 3.5-inch server bays
  • New condition bare drive ready for immediate deployment

Questions about this item

Should I choose the single drive or the lot of 10 for my storage array?

The lot of 10 provides ten 300 GB drives for larger arrays, while a single unit suits a smaller build or a spare.

What does the 15 000 RPM speed deliver in daily use?

The 15 000 RPM rotation gives very low latency and high sustained throughput for transaction-heavy workloads such as databases.

How does the SAS 6 Gb/s interface limit real-world performance?

The SAS 6 Gb/s link caps the maximum burst rate at 6 Gb/s, so sustained speeds will stay below that ceiling.
