How about a couple of comparative tests on intel systems if AMD is supposed to make it faster. It would be nice to see what, if any difference there actually was.

Just a simple question but how are you meant to cool these things if you aren't allowed to remove the sticker? Is the sticker able to transfer heat over to my mobos M.2 heatsinks?

What a weird remark. There aren't any PCIe Gen 4.0 setups actually working on Intel, so everything halts at ~ 3GB/sec due to lane bandwidth. You'll need to wait until Rocket Lake and further future processors for that.

Sorry, but no. It was not weird, or unreasonable. You state the ssd works on PCIe 3.0, so it could have been tested. Not everyone in the market for ssd's own new PCIe 4.0 AMD computers. Some own intel, some own PCIe 3.0 AMD. Seeing how it performs on the majority of systems out there does not seem weird.

I didn't say unreasonable nor did I meant to insult you, but weird I do find it .. why would you buy a PCIe gen 4.0 product and then use it at Gen 3.0. And yeah .. it also works with PCIe Gen 2, .... There's not going to be a difference other than the SSD cannot peak beyond Gen 3 x4 lanes .... ~3GB/sec. Everything below that metric remains the same / is similar.

I think HH is just trying to save you some money. I admire that.

there are some new drives like sn850 that blow the competition out of the water in random r/w performance,using 3.0 would not affect that. I bought a m9pey for its random r/w performance and was getting the same scores on z97 (2.0) as reviews did on z370/z270 with dmi 3.0 that said,this drive is not sn850. and his remark was absolutely fine. would an intel user see much of a difference using this drive ? that is a good thing to ask. seriously,how quickly would that slc cache run out on pcie3 vs pcie4 before you'd be down to tlc speeds ? you think it'd make it woth it ?
Silicon Power’s US70 can absorb over 333GB of data at a rate of 4.2-4.3 GBps before slowing down
from tom's review so you're looking at 330gb of data max, writing at 1gb/s faster on pci-e 4.0 before it runs out. that is about the only scenario where you'll see a difference,and mind you this slc cache will shrink as you fill the drive.at 75% full you'll be left with precious little slc.

Silicon Power ssd's are among the cheapest, generally. These may drop to be the cheapest in their class shortly. So seeing how it compares to something like the 970evo on PCIe 3.0 seems to me would determine whether it's saving more money or 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.)

considering gen 4 nvmes are the only ones able to saturate a gen 3 bus...... why not?

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...
