DELL ST373455SS 73GB 15000RPM SAS internal hard drive

SKU CH-B9DN-DE5DG

A 73 GB 3.5-inch SAS hard drive spinning at 15000 RPM with a 16 MB buffer and an included R Series caddy

  • 15 000 RPM spindle speed accelerates data access
  • 73 GB capacity reduces RAID rebuild time
  • 16 MB cache buffers bursts for smoother throughput
  • 5 inch SAS interface fits standard server bays
  • Includes R-series caddy for direct Dell chassis installation

Dell Cheetah 15K.5 73GB SAS Drive

This new Dell Cheetah 15K.5 internal hard drive delivers 73GB of storage on a 3.5-inch SAS interface. It spins at 15000RPM with a 16MB buffer and includes an R Series caddy for installation. The drive is built for server and high-performance desktop environments.

Suited for transaction-heavy workloads

The 15000RPM spindle speed supports rapid read and write access for email, business processing, transaction processing and decision-support applications. It is not for users who need more capacity than 73GB, who require a quieter drive for a home desktop, or who lack a SAS host bus adapter or backplane.

15000RPM spindle speed decides fit

The single specification that determines whether this is the right part is the 15000RPM rotational speed. That speed defines the drive's random I/O performance and makes it suitable for the high-throughput workloads listed above. If the workload does not demand that spindle speed, a lower-RPM drive may be more appropriate.

Questions about this item

How do I install the 3.5-inch SAS drive with the included R Series caddy?

Slide the drive into the R Series caddy until the connector seats firmly on the SAS backplane, then secure the assembly in a 3.5-inch bay with the supplied screws. The step often missed is fully engaging the SAS connector before tightening the caddy.

What part will need replacement first in a 15000 RPM SAS drive?

The spindle motor bearings typically wear first after years of continuous 15000 RPM operation; plan to replace the entire drive when SMART reallocated-sector counts rise.

What limits sustained write throughput on this 3 Gbps SAS drive?

The 3 Gbps SAS interface caps sustained transfers well below the 16 MB cache and 15000 RPM media speed, so the bus becomes the bottleneck during long sequential writes.
