But to get this cheaper price, NAND is moving to TLC, QLC, and beyond. Lower and lower write endurance, lower and lower actual performance once you run out of cache.
Optane is nearly unkillable, with far more performance. I would like to see price come down, but being realistic, it probably won't. Samsung's Pro drives cost more than their Evos for a reason too.
None, in theory.
NVMe as a standard (as compared to SATA/AHCI) is extremely parallel capable, and they are cached with actual DDR RAM. As long as the controller can keep up, they can just keep throwing more and more NAND at the problem until the link is maxed. We have been making RAID-like silicon for a very long time, so this is nothing new, it's all just on one little chip these days.
But this is all Seq-Read bandwidth... that isn't very real world relevant, which is why even the cheapest NVMe, such as an Intel 660p, does not feel very different from the worlds "best", like the new 4.0 drives.
'unless you do rather large transfers. then you'll see the quality difference.
R.I.P. Zawarudo, may you OC angels' wings in heaven.
If something appears too good to be true, it probably is.
Best R0ach Quote of all time : TLDR: Haswell might be the last legit gaming platform unless mice get their own non-USB interface on some newer architecture.
