When can we expect pci-e 4.0 drives?

[Sampsy]

Do we know whether there will be any pcie-4.0 drives released at the same time as Zen 2? I'm strongly considering upgrading but am not going to bother until everything is available.

Corsair MP600 is due to be released next month AFAIK.

Will these pull away from SATA3 SSDs in terms of basic use? I mean, currently PCIE SSDs are only a second or two faster on boot-up and game-loading times....will these be significantly faster than that? I guess there's not room to be a lot faster (i.e. like the difference between HDDs and SATA SSDs) but 5-10 seconds would be nice.

When six times as fast NVMes are barely any faster, why should extra bandwidth do any good?
Unless you count your bank account/wallet becoming lighter as good...

Main bottlenecks are simply elsewhere than raw synthetic benchmarketing performance.

Yeah, I know nothing about such things. Only seen a shallow article or two and a few comparisons on youtube.

And yeah, the prices are off-putting. I'll probably stick with a bigger (1TB instead of my current 256GB) SATA3 SSD for my next upgrade.

I'd avoid the first load of PCI-4.0 drives, as they offer very little over the performance of a high-end 3.0 drive and are not pushing the 4.0 (4x) PCI-E slot at all. They like to advertise 5GB/s, but even sequential only it will be more like 4.2GB/s, which is good, but you can get 3.0 drives that push 3600 MB/s read/3300 MB's write.

4.0 drives will start to become interesting once Samsung introduce their new controller later in the year, with higher density NAND chips at 128-layers, this will push drive beyond 6.5GB/s, and towards 7.5GB/s by the middle of next year.
