Dell Cheetah 15K.6 450GB SAS Drive

This Dell Cheetah 15K.6 is a 3.5-inch internal hard drive with a 450GB capacity. It spins at 15000RPM and connects via a SAS 3Gb/s interface with a 16MB buffer. The unit is supplied as a bare drive only in new condition.

Suits SAS servers needing 15K speed

This drive fits servers or workstations that require a 3.5-inch SAS connection and 15000RPM performance for transaction-heavy workloads. Buyers whose systems lack a SAS backplane or controller cannot install this unit. It is not intended for external enclosures or laptop bays.

Interface decides compatibility

The 3Gb/s SAS interface is the single specification that determines whether this drive works in a given system. Verify that the host controller and backplane support this exact SAS link speed before purchase.

Questions about this item

Will the 15 000 RPM spindle require periodic bearing service or replacement?

The drive is a sealed unit; the spindle bearings are not user-serviceable and the drive is replaced as a whole if they fail.

Which component hits its limit first during sustained writes — the 16 MB cache or the 3 Gb/s SAS link?

The 3 Gb/s SAS interface caps sustained throughput before the 16 MB buffer becomes the bottleneck.

How much heat and power does the 3.5" 15 000 RPM drive produce when running continuously?

Expect typical enterprise 3.5" 15K power draw and corresponding heat; ensure adequate airflow in the chassis.
