Seagate Cheetah 300GB 15K SAS Drive
The Seagate Cheetah ST3300655SS is a 300GB 3.5-inch internal hard drive spinning at 15000 RPM with a 16MB cache. It uses a SAS 3Gb/s interface and is supplied as a bare drive. This unit is designed for high-performance server environments.
Suited for high-IOPS server workloads
This drive suits administrators deploying storage in transaction-heavy servers where low latency and sustained throughput matter. It is not suitable for desktop PCs or workstations lacking a SAS controller. Buyers needing larger capacities or lower power draw should consider other options.
SAS 3Gb/s interface determines compatibility
The single specification that decides fit is the SAS 3Gb/s interface; the system must provide a matching SAS backplane or host bus adapter. Without that connection the drive cannot communicate. Verify the controller supports this interface before purchase.

Questions about this item
How can I confirm the drive is spinning at 15000 RPM after installation?
Check the SMART data or system BIOS; both will report the spindle speed as 15000 RPM for the ST3300655SS.
The listing says "Bare Drive" — does that mean I need to buy a SAS cable and mounting screws separately?
Yes, the bare-drive package includes only the 3.5-inch unit; a SAS cable, power connector and mounting screws must be sourced separately.
I see only the 300GB 15000 RPM version listed — are there other capacities or speeds for this model?
The ST3300655SS is offered solely as a 300GB 15000 RPM drive; other capacities or speeds carry different model numbers.
