  • 15,000 RPM spindle delivers rapid data access for transaction-heavy workloads
  • SAS 6 Gb/s interface provides high-throughput connectivity to servers and arrays
  • 300 GB capacity stores operating systems, databases and critical application files
  • 16 MB cache buffers bursts to smooth sustained read and write performance
  • 5-inch form factor fits standard enterprise drive bays and hot-swap trays

300 GB 15K RPM SAS enterprise drive

The Seagate Cheetah 15K.7 ST3300657SS is a 300 GB internal hard drive spinning at 15000 RPM with a 6 Gb/s SAS interface and 16 MB cache. It is built for 3.5-inch bays in servers and storage arrays that demand high transaction rates and low latency.

Suited for transaction-heavy workloads.

This drive suits databases, email servers and virtualisation hosts that benefit from 15K RPM response times. It is not for archival or backup roles where capacity per pound matters more than random I/O performance, nor for systems that lack a SAS host bus adapter or RAID controller.

6 Gb/s SAS interface dictates controller choice

The drive communicates over a 6 Gb/s SAS link, so the host must provide a matching SAS port and cable. Without a compatible SAS connection the drive cannot be used, regardless of physical bay size.

Questions about this item

How do I install the ST3300657SS 3.5" SAS drive and what step is often missed?

Mount the drive in a 3.5" bay, attach the SAS data and power cables, then configure the drive in your RAID or HBA BIOS so the 6Gb/s link is recognised.

What maintenance or replacement will the ST3300657SS need over time?

The 15000RPM mechanical mechanism and 16MB cache are sealed; no user serviceable parts exist, so plan to replace the entire 300GB unit if SMART errors appear.

What limit appears first on the ST3300657SS during sustained heavy writes?

The 6Gb/s SAS interface and 16MB buffer saturate before the 15000RPM platters, capping sustained throughput at the interface ceiling.
