Yes I too have noticed their insane floating BOM and what I meant to say was “…and then whatever it was that showed up…”. A while back I spent some time perusing ssd.userbenchmark.com to see if I could discern any hidden bargains matching up the firmware with performance and decided that it was fools mission. It’s much less work just to buy from one of the many other companies that do not play games.

I’m pretty sure V300 got another nand switch after the 20nm sync fiasko.

Because the last time i benched one of those 120GB puppies, it pulled ~4
460MB/s read and ~125MB/s write. No achievable on 20nm async.

Maybe 16nm micron async ?

Here is the proof

This guy does a decent job of tracking that type of info.

Understandably he is non-committal about the V300 but I’m pretty sure it was originally 19nm Toggle before the transition to the 20nm Micron Async or whatever it was that showed up on the Kingston loading dock.
