This happens on ALL operating systems (7, Ubuntu, etc.).
What happens is everything for 1-3 seconds becomes unresponsive, I then hear what sounds like my other internal hard drive 'spinning up', and then viola everything is responsive again.
Note: Already ran SMART tests, no issues at all.
I think issue is that the HDD spins down and when need it gets 'turned-on' (OS settings turn off HDD's after 20 mins of inactivity) and because my pagefile is on the other HDD it causes OS to temporarily freeze.
Need more tips, and insight.
