Alternately, the drive may have a Secure Erase command which takes the guesswork out of the process, but you may need a special manufacturer’s tool to access that command. With SSDs, you need special tools that help to actually wipe it and not leave any stray data around. Technically, even platter hard drives have this issue, but they don’t have the ‘phantom’ space and don’t really have issues with wear-leveling, so you can just write a bunch of 0’s to the drive repeatedly and you’re pretty sure to clear all of the data without ruining the useful life of the drive. What this means when you’re wiping the drive is that even if you delete a file, that file (or at least, a potentially older version of that file) might be sitting somewhere in another flash memory area that has been written too many times. Using these wear-leveling algorithms and the ‘phantom’ extra space, the drives are calculated to last for acceptable amounts of time given standard usage for the given application (i.e., server, home, gaming, etc.). The drive keeps track of how many times an area of flash has been written to, and if one area starts to get more used than another, it will write the data to a different area to ensure that all of the areas have roughly similar use. To lengthen the useful life of the drive, there is actually more storage available on the drive than they tell you.
Basically, SSDs use flash memory which can only be written to a certain number of times before The ‘special SSD wiping ability’ one is interesting. Has special SSD-wiping ability (stretch).There’s a wide variety of tools that will wipe drives for you, but for my purposes, I’m looking for something that is: I need to wipe these so that I can sell them. I’ve got quite a few 256GB SSDs and even a 128GB one sitting around. It’s rather surprising that a few years ago, a 256GB SSD was a good and useful thing to have, and now even 512GB is looking pretty anemic. Among this stuff is a bunch of laptops and SSDs. Added persistence option to Kodachi entry.It’s time to clear out a bunch of old stuff from my basement.
