Silver 3.5 inch SAS hard drive with green circuit board visible underneath

Seagate

Seagate Cheetah 15K.6 ST3450856SS 9CL066 450GB 15000RPM SAS 3.5 internal hard drive

SKU CH-322C-7JM11

A 450 GB 3.5-inch internal hard drive spinning at 15000 RPM with a 16 MB buffer and SAS 6Gb/s interface

  • 15 000 RPM spindle speed enables fast data access
  • 6 Gb/s SAS interface supports high-throughput workloads
  • 16 MB cache buffers bursts for smoother I/O
  • 450 GB capacity fits dense storage arrays
  • 5-inch form factor suits standard server bays

Enterprise SAS storage

This new Seagate Cheetah 15K.6 ST3450856SS is a 3.5-inch internal hard drive built for servers and storage arrays that demand 15000RPM performance. It provides 450GB of capacity over a SAS 6Gb/s interface with a 16MB buffer. The drive is suited for transaction-heavy workloads where low latency and high IOPS matter.

Not for desktop or cold storage

Buyers who need a simple plug-in drive for a consumer motherboard should look elsewhere because this unit requires a SAS controller or backplane. It is also not suited for archival or bulk-media libraries where capacity per pound outweighs random-access speed. The 90-day warranty reflects its enterprise pull-status rather than retail coverage.

15000RPM spindle speed

The single specification that decides fit is the 15000RPM rotational speed, which determines the drive's random-access latency and sustained throughput. If the application cannot use that speed — or the chassis cannot cool it — a slower nearline drive will be more appropriate.

Preguntas sobre este artículo

Does the 3.5-inch SAS drive ship with cables, brackets or a mounting kit?

The drive is sold as a bare unit; SAS data and power cables plus any 3.5-inch mounting hardware must be purchased separately.

When should I choose the 450 GB 15K RPM model over a lower-capacity 15K drive?

Select this 450 GB model when you need the maximum high-speed capacity available in the 15K.6 line for transaction-heavy workloads.

How does the 15,000 RPM spindle speed affect real-world database performance?

The 15,000 RPM rotation cuts average rotational latency to roughly 2 ms, accelerating random read/write operations on the 6 Gb/s SAS interface.
