I use PCIe 4.0 as main drives and backup drive.
My biggest time sink is cloning system for back-up.
Because of throttling, the data transfer is only slightly better then SATA.
It usually takes about 2 hours for clonezilla to create and check a back-up.
It is worth doing, but I wish the hardware was faster.

System Name Bragging Rights
Processor Atom Z3735F 1.33GHz
Motherboard It has no markings but it's green
Cooling No, it's a 2.2W processor
Memory 2GB DDR3L-1333
Video Card(s) Gen7 Intel HD (4EU @ 311MHz)
Storage 32GB eMMC and 128GB Sandisk Extreme U3

Keyboard Logitech MX Keys (not Cherry MX at all)
VR HMD Samsung Oddyssey, not that I'd plug it into this though....
Software W10 21H1, barely
Benchmark Scores I once clocked a Celeron-300A to 564MHz on an Abit BE6 and it scored over 9000.
Finally! \o/

All Gen 5.0 SSDs so far have been stupid because they cannot be cooled without exceeding the M.2 dimensions specification.

Brute forcing the issue with a large heatsink and fan is a really terrible kludge that blocks CPU coolers, PCIe slots, and of course necessitates on of those whiny, tiny, sub-40mm fans that have pitiful throughput and even more pitiful lifespans. Boards that include a PCIe 5.0 M.2 slot so often also include integrated passive cooling that has to stripped off first just to install one of the hot-n-hungry PCIe 5.0 SSDs and if the piece you're stripping off to clearn room for your roasty-toasty PCIe 5.0 SSD's active cooling solution was also the same piece that cooled your PCIe 4.0 drive you also use - then tough luck. One of your drives must suffer and your fancy motherboard now looks like an ugly mess.

I think you're confusing random file transfers with throttling, as random reads and writes aren't that much better on NVMe drives compared to the best SATA drives.
As long as you have heatsinks on your drives, they shouldn't throttle.

That's why you always buy SSDs without heatsinks. In fact, the PCIe 5.0 slot heatsinks on the motherboards are often better than the ones that the SSD makers supply. Not the ones under the GPU though, but you don't really have a choice there.
