The present disclosure generally relates to relocating data in a storage device and updating a compressed logical to physical (L2P) table in response without invalidating cache entries of the L2P table. After relocating data from a first memory block associated with a first physical address to a second memory block associated with a second physical address, a version indicator of a cache entry corresponding to the first physical address in the L2P table is incremented. One or more cache entries are then added to the L2P table associating the relocated data to the second physical block without invaliding the cache entry corresponding to the first physical address. When a command to read or write the relocated data is received, the storage device searches the L2P table and reads the data from either the first memory block or the second memory block.
