the Enclosure I got was a Sabrent so I just went ahead and got the same NVMe with it. I'm sure any would work though. Crucial has one for $99 that tops out at 2000MB/s which is more than the enclosure would see anyway, so there's a place to save money too.
And this is the enclosure I bought
Looks like it went up in price a little bit, I got mine for $35 at the time. but the total is looking like $164 for a 1TB which is still cheaper and faster than T5
Its been a while since I've looked at them because mine works so well, but there's this too, looks prebuilt with the parts I linked to and uses their new enclosure which doesn't require a screwdriver, I might pick up one these up too. $150 for 1TB is pretty decent.
but this is a disclaimer, you'll only see the 980MB/s or so if use plug into a USB 3.1 (gen 2) and you'll only get 580MB/s if you plug into a 3.1 (gen 1) port
