Product identity and audience

This HGST Ultrastar 15K147 is a 73.4GB 3.5-inch internal hard drive with a Fibre Channel interface. It is built for enterprise SAN environments that demand 15000 RPM spindle speed and low latency.

Who this suits and who should look elsewhere

It suits administrators running online transaction processing, data analysis or other multi-user workloads that benefit from 3.6 ms average seek time and 2 ms average latency. Buyers who need larger capacity or a different host interface should look elsewhere.

Single specification that decides fit

The 15000 RPM spindle speed delivers up to 33 percent more I/Os per second than 10000 RPM alternatives, making rotational speed the key figure for deciding whether this drive meets the performance target.

Questions about this item

How do I install the 3.5" Fibre Channel drive in a SAN enclosure?

Mount the 1" high by 0.5" wide by 5.7" deep drive in a 3.5" bay, connect the Fibre Channel interface to the backplane or HBA, and secure the 1.67 lb unit with four screws; the step often missed is confirming the enclosure supplies the correct Fibre Channel signalling voltage before powering on.

What maintenance or replacement will the Ultrastar 15K147 need over its service life?

The 15000 rpm spindle and 16MB buffer are sealed; no user-serviceable parts exist, so plan to replace the entire 73.4GB drive after the 5-year design life or when SMART attributes indicate wear.

What limit appears first during sustained 15000 rpm operation?

The 3.6 ms average seek time and 2 ms latency are maintained until the 15000 rpm spindle reaches its thermal ceiling, at which point the drive throttles I/O to protect the 16MB cache and mechanical components.
