Hibernation.
Win7, Win10.
It's quite common for mining rigs to have "small" SSD, just enough for the OS and Claymore, so probably doable on a 64GB SSD even.
I'm running win7 (w/o hibernation), claymore and very little else on a 40gb ssd. It all just fits, but again, one of those things that was lying around and had no other purpose.
Hahaha, MAN you're hardcore, that is quite an achievement, WOW.
Don't tell MS anyone, they'll be looking for new ways to screw us over, lol.
Side note: Do you limit the Claymore log file size? or overwrite? Or maybe log to a USB storage device?
