Abstract
A method and apparatus are disclosed for automatic solid state drive performance recovery. A detection module detects a first SSD exceeding a fragmentation threshold. A plurality of drives comprises the first SSD and stores a data copy of data stored on the first SSD. An erase module erases a mapping table for the first SSD. The mapping table maps Logical Block Addresses LBA to physical addresses for the first SSD. A rebuild module rebuilds the data and the mapping table on the first SSD from the data copy.
