TL;DR - Does slot size matter when it comes to performance of PCIe to NVME adapters?


Looking to buy a few PCIe to NVME cards as my SATA ports are full and I'd like to add more SSD type storage.

I have had a good experience with a Ugreen X16 slot adapter and a Teamgroup MP44 1TB NVME drive in another PC. That was my first experience with NVME in a PC.

But on this other SFF (small form factor) computer, I only have one X16 slot and I may want to reserve that for a video card.

I would have bought the Ugreen card again but the BF sale price is over and it's back to its normal price.

I do see other options for X1, X4, and X8 cards from other manufacturers.

Is the performance the same with cards with the smaller slots?

I know that theoretically the X16 card would be the fastest but I wonder if the smaller slots would also be able to handle the throughput of the NVME drive (The MP44 is advertised as 7400/6500 MB/s).

I note that the Ugreen has cutouts in its card to allow use in X4 and X8 slots whereas some other brands are only X16.
