Cheetah Drive Cheetah: The
worlds fastest drive. Youd like to integrate it into your system, but
doesnt a 10,000-RPM disc drive require careful attention from a cooling perspective?
Please note. With proper system integration, the Cheetah can maintain the ability to
operate at temperatures similar to Seagates 7,200-RPM Barracuda class drives.
A 10,000- RPM drive will generate more
heat than drives with slower spin rates.The increased heat is primarily due to increased
motor power within the Hard Drive Assembly (HDA). Seagate has, however, defined a
relatively straightforward integration process in terms of cooling this fast cat.
To optimize cooling of the 3.5-inch
ultra-high performance drive, traditional forced-air (or convection) cooling, alone, may
in some cases not be the foremost solution. If a cabinet is marginally designed for
7200-RPM disc drives, there simply may not be adequate air flow to properly cool a 10,000
RPM-model. Adding a fan or two may be an option, but in many cases the increase in noise
may exceed environmental specifications.
Additional fans or air flow may not be
required. By using thermally conductive mounting material, such as metal, a conductive
path is created for the HDA to move generated heat from the drive to the drive canister or
cabinet. By mounting a 10,000-RPM drive with this method on each side of the HDA housing,
direct contact to the HDA allows for a conductive path to occur.
The results are often dramatic. HDA
temperatures can fall by as many as 14 degrees C. By utilizing this method, it can be
practical to then apply the more traditional convection methods.
While the actual air flow required will
vary for each system, Seagate has been working with a large number of customers to
successfully integrate the Cheetah. Indeed, System Integrators and Seagate are convinced
that the Cheetah drive can out perform the competition at manageable temperatures. |
