Abstract
A solid-state drive (SSD) is configured for dynamic resizing. When the SSD approaches the end of its useful life because the over-provisioning amount is nearing the minimum threshold as a result of an increasing number of bad blocks, the SSD is reformatted with a reduced logical capacity so that the over-provisioning amount may be maintained above the minimum threshold.
