Seagate Cheetah 450GB SAS 15K Drive

The Seagate Cheetah is a 3.5 inch enterprise hard drive built for servers and storage arrays that demand high rotational speed. It delivers 450GB of capacity over a SAS 6Gb/s interface with a 16MB cache buffer. The 15000 RPM spindle speed supports low latency for transaction-heavy workloads.

Suits hot-swap bays; not for laptop or USB use

This drive fits 3.5 inch hot-swap drive bays in rackmount servers, SAN or NAS appliances where rapid drive replacement is required. It is unsuitable for laptop installations, external USB enclosures or any system lacking a native SAS host bus adapter. Desktop PCs without SAS controllers cannot use this unit.

15000 RPM spindle speed decides fit

The defining specification is the 15000 RPM rotation rate, which determines the drive's random access latency and sustained throughput profile. Buyers needing lower power draw, quieter operation or larger capacities per spindle should evaluate slower nearline alternatives. The 15000 RPM rating is the primary filter for this part.

Questions sur cet article

How can I verify the ST3450857SS is running at 15000 RPM after installation?

Use SMART monitoring tools or your RAID controller BIOS to confirm the reported spindle speed matches 15000 RPM and that the SAS link negotiates at 6Gb/s.

What comes with the Cheetah 15K.5 drive and what must I provide separately?

The drive ships as a bare 3.5" LFF unit; you must supply a SAS backplane or HBA, compatible cables, and a 3.5" drive bay with adequate cooling.

Which capacity version of the Cheetah 15K.5 should I choose for a high-IOPS database volume?

The 450GB model delivers the full 15000 RPM performance with 16MB cache; select it when you need maximum transactional throughput in a single spindle.
