Abstract
A storage system is provided that performs a defragmentation operation or proactive garbage collection in its memory based on a command from a host. The command specifies which blocks in the memory should take part in the defragmentation operation by specifying a maximum amount of valid data that a block can have to qualify for defragmentation. That way, the storage system only performs defragmentation on those blocks that meet the validity criteria provided by the host. This can help improve performance of the storage system while reducing the degree of negative tradeoffs that may come with defragmentation or proactive garbage collection.
