Abstract: A device may include a SSD having multiple storage units and a deduplication control circuit configured to determine whether selected data content to be stored is a duplicate of previous data content already in a first buffer of data buffered to be stored in a set of storage units. The deduplication circuit may be further configured to, based on a determination that the selected data content is a duplicate of first previous data content already buffered in the first buffer, instead of buffering another copy of the selected data content, buffer a first header including a first pointer that associates the first header with the first previous data content already buffered in the first buffer. The deduplication circuit may also be configured to reorder the first buffer such that individual data contents in the first buffer are grouped near headers associated with the individual data contents.

Abstract: A system includes a read/write controller removably coupled to a storage drive. Responsive to detection of a coupling between the read/write controller and the storage drive, the read/write controller retrieves key information from the storage drive, uses the key information to locate adaptives associated with the primary storage medium, and loads the adaptives into volatile memory to configure read/write settings for access to the primary storage medium.

Abstract: Channel information and channel conditions determined by an Offline Tracking process are used to determine whether or not an adjustment to the read reference voltage can be avoided altogether without detrimentally affecting performance, or, alternatively, to determine a precision with which a read reference voltage adjustment should be made. If it is determined based on the channel conditions that a read reference voltage adjustment can be avoided altogether, read performance is improved by reducing the probability that a read reference voltage adjustment needs to be made during normal read operations. If it is determined based on the channel conditions that a read reference voltage adjustment needs to be made with a particular precision, the read reference voltage is so adjusted. This latter approach is advantageous in that relatively fewer adjustments will be made during normal read operations.
