DELL ST973451SS 73GB 15000RPM SAS 16MB 2.5" internal hard drive with caddy

SKU CH-XVCP-A6B3P

A 73 GB 15,000 RPM SAS drive with 16 MB cache in a 2.5 inch form factor, supplied new with a caddy

  • 15,000 RPM spindle speed accelerates data access
  • 73 GB capacity stores critical operating-system files
  • 16 MB cache buffers bursts for smoother throughput
  • SAS 3 Gb/s interface connects directly to compatible controllers
  • 5-inch form factor with included caddy fits standard drive bays

73 GB 15 000 RPM SAS drive

The Dell Savvio 15K.1 ST973451SS is a 2.5 inch internal hard drive built for enterprise servers and storage arrays. It delivers 73 GB of capacity at 15 000 RPM with a 16 MB buffer and a 3 Gb/s SAS interface. A Dell caddy is included for direct mounting in compatible drive bays.

Suits high-IOPS server workloads

This drive suits administrators who need low-latency random access for databases, transaction logs or virtualisation hosts. Buyers who want more storage per spindle should look elsewhere because the 73 GB capacity is fixed. Systems without a SAS backplane or controller cannot accept this interface.

15 000 RPM spindle speed

The 15 000 RPM rotational speed is the single specification that determines whether this drive meets the performance target. It provides the high IOPS and low access times required by demanding server applications. If the workload can tolerate slower spindle speeds, a different drive class would be more appropriate.

Does the drive ship with the caddy included or must I order it separately?

The listing states the ST973451SS includes the caddy tray, so no extra bracket is required for installation.

Which capacity and speed variant matches the NP657 part number?

The NP657 model provides 73 GB capacity at 15000 RPM with a 16 MB buffer on a SAS 3 Gb/s interface.

What sustained throughput can I expect from the 15000 RPM SAS drive in a typical server?

At 15000 RPM the drive delivers high IOPS for transactional workloads, limited by the 3 Gb/s SAS link and 16 MB cache.
