While not an overly active contributor to the StackExchange network, on occasion while searching for answers to my own questions I'll stumble across questions that I'm familiar with and I'll do what I can to answer them.

comment How do I exit a Modern UI app?
It's not that it's inconvenient....it's that it's UTTERLY AND COMPLETELY UNINTUITIVE that that is what closes an app! Did Microsoft not hire a single UX engineer?

comment Restoring performance and estimating life of a used SSD drive?
Maybe we should never have called it "Garbage Collection" and instead just nicknamed the older, reactive controllers "hoarders".

I'm a bit flabbergasted that so many people are apparently unaware of secure erasing an SSD. It is not necessary to TRIM every single block. Simply run a utility that sends a Secure Erase ATA command to the SSD and your problem is solved, regardless of whether or not the SSD supports TRIM.

Incorrect Jeff, a Secure Erase is completely independent of TRIM. It's an actual ATA command, and it's the only thing you can do to fully restore non-TRIM supporting drives. When an SSD receives this command, all NAND cells are marked as empty, restoring the drives original write performance without the need for TRIM. There are numerous tools available which can do this, including hdparm which is referenced in the top answer thus far.

Not quite Mr Alpha. The term "Garbage Collection" came about from controllers that proactively do the process you describe at optimum times as opposed to simply reacting when they absolutely need to do it (which again, results in bad performance as the drive fills up).

Great write up, but this unfortunately will not work for non-TRIM supporting SSD's. For that you will need to go a bit further. See the ATA wiki at kernel.org for instructions on how to do so with hdparm. It would be even better if you could modify your original entry to include this info :)

Aha! I found the original Anandtech article!
