Abstract
An embodiment of a data storage apparatus includes a storage medium, a flash memory buffer configured to store write data to be written in the storage medium, and a controller configured to compare the amount of unused space in the flash memory buffer to a first reference value, compare the amount of valid data in the flash memory buffer to a second reference value, and in response to the comparisons, conducts either a block reclaim operation on the flash memory buffer or a buffer flush operation to transfer valid data from the flash memory buffer to the storage medium. An embodiment of a method for managing a data storage apparatus includes determining when to perform a reclaim operation on a nonvolatile memory buffer, and performing the reclaim operation by moving data either physically or virtually within the nonvolatile memory buffer.
