Sorry, No, it can't work for me.
What I'm prepared to do is converting all old hard-copy photos to digital photos, adding graphic and text on all photos, creating digital albums etc. There are >1,000 hard-copy photos. I need a portable SSD transferring them between PCs because of the file size.
Then why did you ask if the online transfer would work?
Fine.
Then any solid state drive of sufficient size.
My original and continuing comment was regarding the 980 Pro.
In a proper environment, it is "faster".
Via USB, it is not.
Don't waste money on an uber fast drive that is limited by the whole rest of the interface, primarily the USB.
But, in the time since you first asked this question, I could have transferred 1,000 photos to my NAS, and then out to 3 different systems.
