A system and method for providing erasure code data protection for an array of solid state drives. The solid state drives are connected to an Ethernet switch which includes a RAID control circuit, or a state machine, to process read or write commands that may be received from a remote host. The RAID control circuit, if present, uses a low-latency cache to execute write commands, and the state machine, if present, uses a local central processing unit, which in turn uses a memory as a low-latency cache, to similar effect.

Methods and systems for backing up data to a target device are described. According to some embodiments, the method receives a first set of data packets for backup, where the first set of data packets includes a multiplicity of data chunks. The method further captures footprints of the first set of data packets in a cache disk array. In response to receiving an acknowledgement from the cache disk array indicating the footprints have been captured, the method further initiates a write operation to write each data chunk of the first set of data packets to the target device. In response to receiving an acknowledgement indicating the data chunk is successfully written, the method further flushes the respective footprint of the data chunk from the cache disk array.

A data storage device includes a data storage medium having a plurality of data blocks. A cache includes a plurality of cache blocks. Each cache block includes a corresponding cache block address. A metadata table includes a plurality of table entries for the data blocks, respectively. Each of the table entries is configured to store the cache block address of one of the cache blocks in which data of a corresponding one of the data blocks is written. A bitmap is configured to store statuses of all of the cache blocks, respectively.

The disclosure is related to systems and methods of managing data storage in a memory device. In a particular embodiment, a method is disclosed that includes receiving, in a data storage device, at least one data packet that has a size that is different from an allocated storage capacity of at least one physical destination location on a data storage medium in the data storage device for the at least one data packet. The method also includes storing the at least one received data packet in a non-volatile cache memory prior to transferring the at least one received data packet to the at least one physical destination location.
