Hey, I have a B450 board, and the opportunity to buy a gen 4 SSD for quite cheap. I know I'll be limited to gen 3 speeds, but would it at least work, or would I actually need that full speed support to even use the drive?
Thanks.
i have a computer its nice

As far as I know both PCI-e 4.0 slots and devices are backwards compatible.
A PCI-e 4.0 nvme will work on a 3.0 pci-e slot as far as I know.

But ya. You will be limited to 3.0 speeds until you put it in a matching 4.0 slot. If 4.0 devices didn't work in 3.0 slots there would be a LOT of very disappointed 3080 and 3090 owners who have intel systems lol.

It will still work and unless you are using multipule devices you wont max out the bus on 3.0

As the reply above has stated, PCIe is backward compatible. I would just like to point out that for that there are faster NVME SSDs on the market from Sabrent and Samsung for about the same price or just buy a significantly cheaper gen3 SSD that is slightly slower. Of course, this is assuming you didn't already buy the drive or have it on hand.

I put a Corsair M600 Gen 4 drive into my EVGA Z270 FTWK (before the board died) and the write speed was substantially higher than the Samsung 960 Pro Gen 3 I had as my boot drive. The read speed is faster too, just not as impressive. The difference between either NVMe Gen 3 or Gen 4 is insane when compared to a HDD. Transfer between drives is lightening speed between NVMe. Postal Speed between the HDD...
Now running a MSI z590 Pro mb and a i7-10700K cpu, in Gen 3:
960 Pro 3313 read/2117 Write
MP600 3472 read/3256 write
ST4000 148 read/142 write (Seagate 4GB storage HDD)
Tried to attach screen shots, not successful.
