this is so funny to me for so many reasons. i found it on reddit i have to share.
little joke explanation - Assuming these are true nvme drives and not just SATA drives with similar keying (ie m.2 sata)... One of those connections has got to be power, the other has got to be data. I'm no expert in offbrand cheap things like this (i mean i have a couple they work for what they do lol) but presumably that's a USB 3 (if even, i bet it's usb2) connection to the computer. i doubt it's exposing any of the pcie stuff over thunder port either. so you have these super fast ssds bottlenecked by usb speeds, god knows what the controller on this cheap piece of shit is so you may not even be able to get smart data from it (sometimes you can but i've noticed it can get really weird) not to mention this looks like a cheap knockoff so i doubt it's usb gen 3.2 with the most performant implementation of spec :harold:
@artemist "You can't really implement NVMe to USB bridges badly" say that to the people who leave out Quality Assurance, with boards that have things like broken traces and so forth. A lot of the cheap electronics on amazon are cheap for a reason. I don't particularly recommend going and paying $$$ for something like a namebrand dock there's definitely offbrand offbrands that feel so bad in terms of quality. Usually you only see that on wish, etsy though.
@artemist not to mention there's just vendors that don't even put chips on the board they just leave them haphazardly? I've seen some shit lol. I mean, I have one of these cheap nvme enclosures. I used it to clone an nvme, it did its job. I would not use it to have dual nvme access on my host computer though lol, that's when you should be looking at name brand solutions or figure out what you're trying to accomplish. I prefer these cheap shitty docks because most of the time i just use them to plug in a drive to see if it's alive, maybe check the smart data. not much storing or retrieving data which would be my main concern for bottleneck.
