Not sure if it matters but I have Libreboot installed. It's the slot located next to the drive slot.
Also any other upgrade recommendations while I'm at it? I have maxed out the RAM and have an SSD. I am wondering if I should upgrade the WiFi card. I don't know if there are any limitations there.
I've seen something similar. What I gotten from that is the fact above only applies when you're using it as an accelerator (as intended).
Yes, it would function as a drive, at least under Linux.
Once again, I haven't actually used this thing..
