As SSD is getting cheaper, I find myself keep thinking that I should buy a bigger one.
But this isn't really a decision based on actual need - and I can tell my mind is playing tricks to convince me that "you need to get it because what if you want to install a lot of large games".
I'm thinking may be a reasonable criteria instead is to see my current utilization, and buy one only if the utilization exceeds a percentage - say ">80% disk util=> buy a new one" as a rule?
With (350GB + 700GB) just over 1 TB of free space between 2 disks, I struggle to see why you would need more, even if you start downloading a bunch of games.
