1. A method to utilize an external memory device to improve performance of a computing device having a rotating storage device comprising: detecting when the external memory device is available for use by the computing device, the external memory device comprising a plurality of external memory devices; prioritizing sectors to be installed on the plurality of external memory devices by populating a selected external memory device from the plurality of external memory devices with a copy of a sector from the rotating storage device, the sector having a higher probability of being accessed, the probability of being accessed corresponding to a historical usage of the sector, and the selected external memory device having a greater bandwidth and less latency in comparison to other external memory devices of the plurality of external memory devices; and redirecting an I/O read request from the computing device or an application for data that is stored on the sector to be read from the selected external memory device transparently to the computing device or the application.
