We’ve seen well known SSD manufacturers switching from reliable MLC NAND to planar TLC trash within the same model (and zero notice to potential buyers). While some OEMs do note the change at least in the revision number, the rest will just quote the small print allowing them to “change specifications at any time without prior notice”. Quite a few manufacturers play tricks with consumers, releasing a certain SSD model with top notch specifications only to downgrade them at some point during the production cycle (but certainly after receiving its share of glowing reviews). In that article, we assumed that manufacturers’ specifications of certain SSD models remain similar for a given SSD model. In our previous article Why SSDs Die a Sudden Death (and How to Deal with It) we talked about SSD endurance and how it’s not the only thing affecting real life reliability.
