Little confused here. Sounds like you were wanting to partition the SSD using MBR rather than GPT? If so, curious as to why? Is Windows 10 the only OS you are going to run? I wouldn't see why you wouldn't want to go ahead and use GPT on any size drive.
I installed 10 with GPT on a SSD instead of MBR even though it's only 500GB
Question is, the main reason for GPT is for 2TB+ drives thus is there any real benefit for your OS?
It's newer and more hardy then MBR so why not, right?
Yes, only 10.
Various benches it's not faster or slower then MBR that I can tell.
I read some mention about some programs that rely on MBR might not work.
So far I've installed a handful of programs and games and no issues.
Maybe somebody can elaborate on that theory more or if it's just certain circumstances.
