Dell Cheetah 15K SAS Drive

The Dell Cheetah ST3450857SS is a 450GB 3.5-inch internal hard drive spinning at 15000 RPM. It uses a SAS 6Gb/s interface and includes a 16MB buffer. This new drive targets servers and workstations that need fast random access for transactional workloads.

Verify SAS Controller and Bay

Confirm your system has a compatible SAS controller or backplane that supports 6Gb/s operation. The drive requires a standard 3.5-inch drive bay and appropriate power and data cabling for SAS connectivity. It is supplied as a bare drive without brackets, rails or cables included.

Sustained 15K RPM Operation

At 15000 RPM the drive maintains high throughput during extended read and write sequences typical of database and logging tasks. The 16MB cache helps smooth burst activity but sustained performance relies on the mechanical spindle speed. Mechanical drives at this speed generate more heat and vibration than slower models.

Questions about this item

What comes in the box with the Dell ST3450857SS and do I need any extra cables or brackets?

The drive is supplied as a bare 3.5in SAS unit only; no cables, brackets or screws are included and must be sourced separately.

Should I choose the 450GB 15000RPM model or a lower-capacity alternative for my server?

The 450GB capacity paired with 15000RPM and 16MB cache is the only version listed, giving the highest throughput for transaction-heavy workloads.

How does the 6Gb/s SAS interface and 15000RPM speed perform in a real Dell server?

The 6Gb/s SAS link and 15000RPM platters provide low latency and high sustained transfer rates for database and virtualisation tasks.
