Abstract:
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, wherein the external memory device comprises a plurality of external memory devices; populating a particular external memory device from the plurality of the external memory devices with a copy of a sector of the rotating storage device, wherein the particular external memory device has at least one of a higher bandwidth or a lesser latency than another external memory device from 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 external memory device transparently to the computing device or the application, wherein a time to read data from the copy of the sector populated on the external memory device is less than a time to read the data from the sector of the rotating storage device.
