I've tried looking for a similar topic, couldn't find one. I was wondering if the Optane would boost all partitions on a main HD or only the current OS partition being used, I have an 750Gb HD with 3 main partitions, one for Windows7, one for Ubuntu and the last for sharing files between the two OS's. I'm researching if it's worth it to buy one optane or one SSD instead to go with my HD.
