Abstract
A data storage device includes an unmap command analysis system that dynamically determines a size, or a LBA range, of an unmap command executed on the data storage device. The size of the unmap command is based, at least in part, on an amount of random data stored by the data storage device. The unmap command analysis system determines whether to check the amount of random data stored by the data storage device in response to a trigger event. When the trigger event is detected and the amount of random data is determined, the unmap command analysis system compares the amount of random data to information in an unmap command size table. The unmap command size table indicates which unmap command sizes are most efficient based on the determined amount of random data stored by the data storage device.
