Seagate Cheetah 15K.6 300GB SAS Drive

The Seagate Cheetah 15K.6 ST3300656SS is a 300GB 3.5-inch internal hard drive built for enterprise servers. It spins at 15000 RPM with a 32MB cache and connects through a SAS interface. This bare drive is sold new as end-of-sale stock.

Server Workloads and High-Speed Access

This drive suits administrators who need fast random-access performance for transactional databases or high-I/O server applications. The 15000 RPM spindle speed and SAS interface support demanding, continuous workloads. Buyers who need larger capacity per spindle or a different interface should consider other options.

15000 RPM Spindle Speed

The 15000 RPM rotation rate is the key specification that determines whether this drive meets your performance target. It delivers the low latency and high throughput required for primary server storage tiers. Verify that your controller and backplane support this speed before purchase.
