Abstract
A solid state drive includes a dual buffer for buffering incoming write data prior to committal to a non-volatile memory. The buffer is operated to provide a temporary backup of dirty data pending successful completion of a host transfer. The dual buffer may be operated as a primary buffer and a secondary buffer. The primary buffer may be used as the default buffer during normal operation. The secondary buffer is written to during a host transfer that is a cache write to dirty data. A copying process may be used to copy data between the primary and the secondary buffer to preserve the backup data pending successful completion of the host transfer.
