Overview

Dual-port SAS at 6Gb/s and a 15,000 RPM spindle define the Seagate Cheetah 15K.7 ST3300657SS. It holds 300GB in a 3.5in LFF drive.

The dual ports let the drive connect to two controllers or paths, which storage arrays use for redundancy. The sector format is 512 bytes, with 520 and 528 selectable. That option matters to arrays that format drives with larger sectors for their own checksums.

Other specs: 16MB cache, a maximum transfer rate of 204 MB/s, an MTBF of 1,600,000 hours and an annualized failure rate of 0.55%. The drive has no encryption.

It suits servers and arrays that already run 15K LFF SAS drives and need a matching replacement or spare.

We offer the ST3300657SS New, Refurbished or Used. New and Refurbished include a warranty of 1 year or 3 years. Used includes 90 days.
