    Abstract: A data buffer adjustment method for a solid state drive is provided. The solid state drive includes a power supplying unit, a monitoring unit, a controlling unit, a cache unit and a storage unit. An accessing electrical energy from a first power source module or a second power source module is selectively supplied to the power supplying unit. In case of power interruption, the accessing electrical energy allows data to be written from the cache memory to the storage unit. The data buffer adjustment device includes the following steps. Firstly, the monitoring unit monitors a capacity for storing electricity of the second power source module. According to the capacity for storing electricity, a size of a temporary storage space of the cache unit is dynamically adjusted. According to the size of the temporary storage space, an amount of the data is determined.

  • Publication number: 20170090782
    Abstract: A writing management method and a writing management system for a solid state drive are provided. The writing management method includes the following steps. Firstly, plural write commands are transmitted to a firmware so as to write at least one data to the solid state drive, wherein each of the plural write commands contains a logical block address and a sector count. Then, the logical block addresses and the sector counts of the plural write commands are sequentially stored to the firmware. Then, an application program sequentially reads the logical block addresses and the sector counts. Then, a sequential write ratio is determined according to the logical block addresses and the sector counts. Afterwards, the application program updates the firmware to a first firmware according to the sequential write ratio.

  • Patent number: 9600293
    Abstract: A logic block addressing (LBA) configuration method and a non-volatile memory device having the same are provided. The non-volatile memory device determines one of logic zones configured in an LBA table according to the number of booting times. The selected logic zone corresponds to a data zone configured in a physical volume. The non-volatile memory device accesses data stored in the data zone in the selected logic zone. Accordingly, in each boot, the instant disclosure provides the LBA configuration method and the non-volatile memory device having the same, which can show data stored in the different data zones of the physical volume to simplify user operation and avoid the user maliciously destroying or erroneously deleting other data stored in the unused data zones of the physical volume, thereby enhancing the efficiency of the non-volatile memory device executing the multi-booting.
