Mechanisms, including systems, methods, and media, for
processing sub-
indirection unit sized data in a
solid-state drive (SSD) are provided, the methods including: identifying, in a first portion of storage of the SSD, a plurality of
indirection units each containing sub-
indirection-unit-sized data and padding; combining the plurality of indirection units into a page-size
data structure using a hardware processor;
copying contents of the page-sized
data structure to a second portion of storage of the SSD; and updating a
data structure relating
logical address of data to physical locations of data so that an entry corresponding to the sub-indirection-unit-sized data of one of the plurality of indirection units changes from having a
physical address in the first portion of storage to having a
physical address in the second portion of storage.
