8GB/s is the max bandwidth from a standard nvme x2 pcie 4.0, and at 7.4GB/s this ssd is already close to maxing it out :)
I'm not good at converting IOPs to MB/s but 650k/740k IOPs for 4kb random r/w seems to be about 3GB/s which seems impossibly good, unless I've messed that up.
It's probably with 64 threads or more loading up the SSD.
I'm definitely interested in these drives, Rainer seemed like it was going to compete with the big boys back in 2020, so it will be interesting to see where it lands now.
Give me a 4TB one of these, and I have my new drive for the next 2-3years until PCIe5.0 stuff starts becoming available.
Just a typo, I'm sure, but PCIe 4.0 is 8GB/s (ignoring overhead) using 4 lanes, not 2.
I like the peak on the S70 getting close to it for read at 7400. I did hear of the newly-announced Kingston "Ghost Tree" SSD getting higher write at 7000, which would beat this one at 6400. I don't know what controller the Kingston one might be using, though. It was 7000 for read, so this Innogrit controller is doing better at 7400. Either way, it's all probably being measured at QD32/64, not QD1.
I still want to see a consumer release for the Alder Stream 2nd-gen Optane, like a "920p" model. That should give you some nice peaks as well but it's going to give you the performance & low latency at QD1. Price it at a decent range (maybe 980 Pro range?), and I'd buy it right away for personal use!

How did it take this long to hit the market? Been using this SSD for more than a month now
