  • 15,000 RPM spindle speed enables rapid data access
  • 300 GB capacity stores critical enterprise workloads
  • SAS 3 Gb/s interface integrates with existing server backplanes
  • 16 MB cache buffers bursts for consistent throughput
  • 5-inch form factor fits standard drive bays

Enterprise SAS Drive

The Seagate Cheetah 15K.5 ST3300655SS is a new 3.5-inch internal hard drive with a 300 GB capacity and a 15 000 RPM spindle speed. It connects through a SAS 3 Gb/s interface and includes a 16 MB buffer. The bare drive weighs 2.0 pound and carries a 90-day warranty.

Who Should Consider This

This drive suits servers and storage arrays that require a 3 Gb/s SAS connection and can accommodate a 3.5-inch form factor. It is not for systems that lack a SAS host adapter or that need a different physical interface. Buyers who need more than 300 GB of space should look at higher-capacity models.

Deciding Specification

The SAS 3 Gb/s interface is the single specification that determines whether this drive will work in your chassis and controller. Verify that your backplane or HBA supports this exact signalling rate before purchase.

Questions about this item

How do I install the ST3300655SS in a 3.5" SAS bay, and what step is often missed?

Mount the bare drive in a 3.5" bay, connect the SAS data and power cables, then ensure the host controller detects the 3Gb/s link speed before formatting.

What maintenance or replacement will the ST3300655SS need after extended operation?

The 15000RPM mechanical mechanism and 16MB cache are not user-serviceable; plan to replace the entire drive once SMART attributes indicate wear or performance drops.

What limit appears first on the ST3300655SS during sustained heavy writes?

The 3Gb/s SAS interface caps sustained throughput, so the 15000RPM platters and 16MB buffer will hit that interface ceiling before thermal throttling engages.
