Re: I wouldn't normally post a Linus link
What's happening is, they're pushing physics and error-correction technology in an effort to make it cheaper (oh, and the usual industry attempts to get the engineering done as cheaply as possible - overstretch the good guys, minimise testing etc).
All standard engineering tradeoff stuff. QLC might actually suit most consumer workloads OK - where the SSD is usually only part-filled and rarely overwritten anyway. Enterprise drives have different optimisations (overprovisioning, MLC, ...).
You should be aware that Very Similar Stuff happens on spinning rust. It's not simple either - they do things like orient the molecules vertically to squeeze more in a small space, but again they know that the physics is on the margins so they store a lot of ECC data. However in the small-% of times it has to rescan the media, you incur 5ms for the disk to spin.
