ESTIMATING ACCESS FREQUENCY STATISTICS FOR STORAGE DEVICE

摘要

Techniques are disclosed relating to determining statistics associated with the storage of data on a medium. In one embodiment, a computing system maintains a management statistic for a storage device, and uses the management statistic as a proxy for a workload statistic for a storage block within the storage device. In some embodiments, the storage block is a first storage block included within a second storage block of the storage device. In one embodiment, the management statistic is a timestamp indicative of when a write operation was performed for the second storage block; the workload statistic is a write frequency of the first storage block. In one embodiment, the management statistic is a number of read operations performed for the second storage block; the using includes deriving, based on the number of read operation, a read frequency for the first storage block as the workload statistic.
