Have a look at this article from Anandtech.com:
| The [Intel SSD DC] S3700 has 264GiB of NAND on-board but only exposes 186GiB
| of it (200GB advertised capacity) as user accessible storage, the rest is
| used as spare area to improve performance, consistency and endurance.
There are numbers for other SSDs in that article.
