Abstract
Techniques for persisting a logical address-to-virtual address table in a solid state storage device are presented. An example method includes receiving a request to write data to a logical block address (LBA) in a memory component of the solid state storage device. The data is written to a location identified by a virtual block address (VBA) in the solid state storage device. The VBA is stored in a rotating dump table in a reserved logical unit of the solid state storage device. A mapping between the LBA and the VBA is stored in a rotating journal table located in the reserved logical unit. The rotating journal table is buffered such that a number of journal entries are stored in a buffer until a threshold number of journal entries are committed to the rotating journal table. A pointer to a current address in the rotating journal is stored in the buffer.
