Got a used HP Probook laptop. Just needs a new drive. HP specs say it has an m.2 2280 slot. So that’s what I ordered. Guess I needed to look closer.
edit: Thanks for all the info, guys. Different types of keys are explained here. Gonna have to look for a sketchy no-name brand.
Story of my past couple months. There are five different products named “g4 dock”, four of which are newer than the G5 dock.
The OLD g4 dock, and then 120W/280W Thunderbolt variants that are either TAA approved or not. One of these four has a 2.5GB Intel NIC. Good luck figuring out which one because they merged the specsheet for all four of them.
