Abstract:
A system, method and apparatus directed to fast data storage on a block storage device. New data is written to an empty write block. If the new data is compressible, a compressed version of the new is written into the meta data. A location of the new data is tracked. Meta data associated with the new data is written. A lookup table may be updated based in part on the meta data. The new data may be read based the lookup table configured to map a logical address to a physical address. Disk operations may use state data associated with the meta data to determine the empty write block. A write speed-limit may also be determined based on a lifetime period, a number of life cycles and a device-erase-sector-count for the device. A write speed for the device may be slowed based on the determined write speed-limit.
