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 Linux

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.
7-men syzygy size 16.7 TB
. CPU bench: 190.384.961 nodes/sec - nice.
