Dell Cheetah 15K.5 73 GB SAS drive

This new 3.5-inch internal hard drive delivers 73 GB of storage at 15 000 RPM over a SAS 3 Gb/s interface. It is built for servers and workstations that need fast random-access performance in a standard large-form-factor bay.

90-day tested unit ready for installation

The drive ships as a tested unit with a 90-day warranty, so it can be installed immediately without additional burn-in or verification steps. No extra cables, brackets or software are included in the package.

Questions about this item

Will the 15000RPM spindle motor or SAS interface require periodic servicing?

The drive is a sealed 3.5 inch SAS unit with no user-serviceable parts; if the motor or controller fails the whole drive is replaced.

What is the first limit reached during sustained transfers on the 3Gb/s SAS link?

The 3Gb/s SAS interface caps sustained throughput before the 15000RPM platters become the bottleneck.

How much heat and noise does the 15000RPM mechanism produce in all-day operation?

At 15000RPM the drive runs warmer and louder than slower SAS models; plan for active airflow in the 3.5 inch bay.
