2. Trim (computing) - Wikipedia

   en.wikipedia.org/wiki/Trim_(computing)

   Because of the way that many file systems handle delete operations, by flagging data blocks as "not in use", [7] [8] storage media (SSDs, but also traditional hard drives) generally do not know which sectors/pages are truly in use and which can be considered free space. Contrary to (for example) an overwrite operation, a delete will not involve ...

3. Write amplification - Wikipedia

   en.wikipedia.org/wiki/Write_amplification

   The actual benefit of the TRIM command depends upon the free user space on the SSD. If the user capacity on the SSD was 100 GB and the user actually saved 95 GB of data to the drive, any TRIM operation would not add more than 5 GB of free space for garbage collection and wear leveling.

4. Solid-state storage - Wikipedia

   en.wikipedia.org/wiki/Solid-state_storage

   A solid-state drive (SSD) provides secondary storage for relatively complex systems including personal computers, embedded systems, portable devices, large servers and network-attached storage (NAS). To satisfy such a wide range of uses, SSDs are produced with various features, capacities, interfaces and physical sizes and layouts. [4]

5. X25-M - Wikipedia

   The X25-M SSD. The Intel X25-M was a line of Serial ATA interface solid-state drives (or SSDs) developed by Intel for personal computers, announced in late 2008. The SSD was a multi-level-cell solid-state drive available in a 2.5" form factor, came in 80 GB and 160 GB capacities and utilized NAND flash memory on a 50 nm process. The second ...

6. Data remanence - Wikipedia

   en.wikipedia.org/wiki/Data_remanence

   Data remanence is the residual representation of digital data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written to the media, or through physical properties of the storage media that allow previously ...

   A Mushkin 1TB 2280 NVMe SSD. 2280 is the most common size for NVMe SSDs. However, 2230 NVMe SSDs are becoming more common to save space in the system board. A SSSTC 256GB 2230 NVMe SSD. Since 2020, Dell (and others) started to use 2230 SSDs in their laptops instead of the more common 2280 size to save space.
