Does anybody know what performance numbers we need to see for a new generation of SSD to noticeably impact gaming performance ? So far from my limited reading, Gen 5 and even Gen 6 won't offer any advantage in terms of performance, with Gen 4 being sufficient. The only advantage of Gen 6 will be a reduction in lanes, thus allowing for more devices and USB slots to be fully powered.

lol; there isn't a notable difference between SATA and NVME for gaming
Flaimbot@reddit
my educated guess is that before the bandwidth/iops were the limiting factors. now we reached a point that decompressing the data is now the bottleneck, thus either a lighter compression algorithm or faster cpu are needed, or the bandwidth (somewhere between the ssd and) into the vram is now limiting the improvements

When can we expect PCIE 6.0

The only significant improvement these new SSDs are making is in sequential read/write performance, 4K random at QD1/2/4 is bound by NAND latency. Consumer workloads like gaming are mostly bound by 4K random at low queue depths.

You just need Microsoft to remove their thumbs from their asses more than anything

It's almost certainly a software problem that we're not seeing any noticeable differences in actual gameplay.
There is no hardware reason that I know that explains why the one noteable Direct Storage game (Ratchet & Clank Rift Apart) has faster in-game loading times when Ratchet falls through the portals into another dimension than for example my 2TB Kingston Fury Renegade which has some of the very best.

Does anyone know what makes Samsung’s controllers able to do this?
The 9100 Pro was already capable of ~2.5 million IOPS and ~15GB/s reads/writes.
InevitableSherbert36@reddit
Are they ahead of the competition?
In TechPowerUp's testing, the 9100 Pro is far from the best in 4K random read, 4K random write, and 4K random read/write. And in real-world performance, four drives with non-Samsung controllers are faster.

I guess further efficiency gains are nice for the data center but realistically as a consumer the SM2508 is all you need as can be seen in the WD_Black SN8100.
Verite_Rendition@reddit
Keep in mind however that SM2508 is a high-end, 8 channel controller. SM2524XT is a 4 channel DRAM-less design. So if Silicon Motion can deliver similar performance with a cheaper controller and fewer NAND dies, then that means consumers will not need quite as of an expensive SSD.
