I shudder to think of the P/E cycle endurance. QLC is already abysmal at 100-1,000 or so so if the SLC-MLC-TLC-QLC trend holds, it will be in the order of 10 or so in the first generation.
I think those numbers are only if you’re doing sub 64k writes no? The data sheets I had seen have QLC numbers very competitive if you could maintain 64k writes.
