HGST Speeds Disk Design Work By 90X
One particularly pesky workload is called MRM, which is a homegrown application that runs on Linux that simulated magnetic recording media. This MRM suite is used to help design the magnetic heads that float over rotating disk drives at the end of electronic armatures. These heads read and write data to magnetic material that is sputtered onto the disk platters, and there is a lot of complex fluid dynamics and magnetism that makes the device work at the incredibly high rotations and low tolerances between the head and the platter. For all the talk about the wonders of flash, a mechanical disk is really an engineering marvel.
