We review the Silicon Power US70 1TB PCIe Gen 4.0 SSD. It among the best performing NVMe SSDs we have tested to date, rating at 5 GB/sec. Of course, it is an SSD you can seat into any PCIe 3.0 compatible PC, however, if you place it into a compatible Ryzen processors B550/X570 based PC, some magic happens as you are running 4000 to 5000 MB/s numbers and higher, thanks to the new PCIe 4.0 interface and a little TLC from Phison, well Toshiba strictly speaking.

considering gen 4 nvmes are the only ones able to saturate a gen 3 bus...... why not?
No one is going to buy a PCIe4 NVMe drive to try and run it on a PCie3 bus... 
Ridiculous! Nope, you'd buy a PCie3 drive if limited to a PCie3 bus. Besides, I don't think you can--the NVMe bus on my motherboard (x570 Aorus master) autoconfigures to the device--there's no way to test a PCie4 NVMe on my motherboard @ less than PCIe4. To do that you'd have to find a system limited to PCie3 and incapable of PCIe4--stick it in that and run it. Guaranteed to run slower. Of course. NVMe drives do not work like GPUs--you can take a discrete PCie4 supporting GPU with its own onboard ram and it will run as fast on a PCIe3 bus because the onboard ram on the card runs much faster than even the PCIe4 system bus--that's why GPUs today have so much local ram in the first place. On my PCie4 motherboard, when you put the GPU slot into PCie3 mode--the rest of the system-wide bus stays up at PCIe4 performance, and only drops down to PCie3 if the device itself is a PCie3 device (and cannot run on a PCIe4 bus.)

Why not?
I don't want a 2 TB PCIE 3 drive that is as slow as molasses once it fills up its cache. The WD SN850 blows everything out of the water because it does not slow down in speed like the Sammy 980 Pro does. It's a bit funny that the 960 Pro keeps its speed faster than the newer Samsung drives...
