I'm interested in people's actual experience with the various NAND Densities. My first SSD was a 60GB Corsair Force II SATA drive bought in 2011. I'm pretty sure it's MLC, but might be SLC. All I know is, it still works. It's slow and tiny by today's standards, but for a homemade NAS, it still works fine even after being used as a main boot drive for 3 or 4 years, then still running as a boot drive for other things ever since. These days, I almost exclusively use TLC. Though I remember the argument years ago that TLC just isn't as durable or reliable as MLC, and some niche cases (OCZ drives) possibly caused that belief. I have TLC Drives still running that are around 5 years old with regular use, and I've had no issues. Now, the same argument is being made with QLC drives. I see Intel's 2TB 660p NVMe drive for under $200, and I think why not? It has a DRAM buffer, it uses an MLC caching system, the speeds are very similar to TLC in most real-world cases, and 5 year warranty. Unless you're regularly transferring 100GB+ files, I don't see how this thing couldn't be an answer for FINALLY getting back to a system with a single storage drive. The only downside is the QLC NAND, which might just be another hyped situation because there were a few crappy models on the market once upon a time. If anyone has some real experience or thoughts with QLC durability/reliability, post here. I'm not really interested in performance discussion, because that's going to be more of an issue with the controller and (lack of) DRAM.
