Abstract: A flash storage device includes a flash storage for storing data and a controller for receiving a command in connection with user data and selecting a sector size associated with storing the user data. The controller allocates the user data among data sectors having the sector size and writes the data sectors to the flash storage. In some embodiments, the controller generates system data and stores the system data in the data sectors or a system sector, or both.

Abstract: A flash storage system includes a data buffer configured to receive and store a data block having data portions. The system further includes flash storage devices having storage blocks interleaved among the flash storage devices and a controller coupled to the data buffer and the flash storage devices. The controller is configured to initiate data transfers for writing the data portions of the data block asynchronously into the storage blocks, where the data transfers for writing the data portions of the data block asynchronously into the storage blocks include reading the data portions of the data block from the data buffer serially and writing the data portions of the data block into the storage blocks in parallel.

Abstract: Methods and systems for wear-leveling in flash storage devices are provided. A flash storage system performs wear-leveling by tracking data errors that occur when dynamic data is read from a first storage block in a first flash storage device and moving the dynamic data to a second storage block in a second flash storage device. Additionally, wear-leveling is achieved by identifying a third storage block containing static data and moves the static data to the storage block previously containing the dynamic data.
