PROBLEM TO BE SOLVED: To improve solid-state storage device utilization.SOLUTION: A method for a managing persistent storage device includes selecting a page for a proactive read request, where the page is located in the persistent storage device. The method further includes; issuing a proactive read request to the page; receiving, in response to the proactive read request, a bit error value (BEV) for data stored on the page; obtaining a BEV threshold (T) for the page, where T is determined using a program/erase cycle value associated with the page and a retention time of the data stored on the page; making a first determination that the BEV is greater than T; identifying an m-page based on the first determination, where the m-page is a set of pages and the page is in the set of pages; and setting the m-page as non-allocatable for future operations.SELECTED DRAWING: Figure 4 |
