Abstract
A method and system for accessing a storage medium that factors in read statistics of previous reads of the storage medium is provided. An access system tracks read statistics generated from previous attempts to read data of the storage medium, which may be stored on a per-unit basis. When the access system receives a request to read data of the storage device, the access system may generate a read plan for the read based on analysis of the read statistics. A read plan may specify the initial speed of the attempt to read the data. The access system uses the read statistics to help reduce the time needed to read a unit of data from the storage medium.
