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.
