I read that there would be a 2TB 980 Pro with part number MZ-V8P2T0BW, but I have yet to see any official release date or product specs. Is it still happening or should I just get the 1TB model instead?
One thing to bear in mind: The Samsung NVMe driver doesn't support the 980. I installed my drive, used a Macrium backup image onto the new drive, but the PC wouldn't boot - the 980 MUST have the standard MS NVMe driver installed prior to imaging - either uninstall the Samsung driver before making the image, or boot from the old drive with the 980 installed, Windows will install the MS driver automatically. You can then image or clone to the new drive.
The 3.3 driver is a year old and not compatible with the 980. Hopefully Samsung will eventually release a new driver with proper support. What you plan will work as Windows will install the Standard NVMe controller driver when it detects the new drive. I did it wrong as my image didn't have the MS driver installed.
