![]() ![]() ![]() You can’t require an SSD sector without erasing it first (TRIM is an optimization that speeds this erasure and reallocation and reassignment processint), and wear-leveling for relability and for performance means thatnyou can’t even address the contents of deleted SSD sector.įull disk encryption further means that the entire contents of the SSD are inaccessible, absent the credentials necessary to decrypt and access the volume. SSD storage is fundamentally very different from how HDD works, how sectors are mapped and are freed for reuse, and particularly around how thr floppy-disk-era sector overwrites and related practices simply serve to further wear the device for no tangible benefits. All freed blocks are necessarily erased, as part of preparing that same storage for re-use. With SSD storage and its use of TRIM, all deletions are secure.
