Abstract
A method for predicting logical blocks address (LBA) information, including: receiving, by a Solid State Drive (SSD), a trace sent from a host, wherein the host can acquire the trace in a reusable environment; determining, by the SSD, one or more LBAs received by the SSD according to the trace; obtaining, by the SSD, a distribution of the LBAs by learning the LBAs based on a preset learning algorithm; and predicting, by the SSD, one or more subsequent LBAs based on the distribution of the LBAs. As a result, it can perform heat classification and prediction of the following LBA used in the SSD by means of learning the LBA distribution of the SSD in a certain reusable environment of the host, thus to improve the hit rate of reading and writing and the efficiency of classification of hot and cold data in garbage collection.
