Is that even right? The minimum size for a HDD I can get is 500GB, and even then the guy said that for $5 more he'd give me the 1TB one so I went for it
I didn't know they still made 15GB ones.

There's a software upgrade as well:
You read right: instead of SSD, the Syzygy tablebases will be cached directly in the RAM for faster access. The switch to Linux is going to provide more stability for the engines and additional speed in terms of Nps. With Linux the TCEC admin can also accept source code submissions for engines.

I wonder why though. I mean if you play a match on old hardware vs new hardware wouldn't the results be pretty much the same?

Why not 6-men syzygy in RAM + 7-men syzygy on SSD?
Even I have now the complete 5 and 6-men syzygy tablebases on my iPad Pro in the SmallFish Chess for Stockfish app.
