I'll be getting a new laptop soon and I'm wondering what the differences are between these two SSDs. I'll probably be putting them in a Sager NP9377 from xoticpc.com. Both SSDs cost the same price but the Samsung 850 EVO has 120 GB vs Micron M600's 128 GB (both for $100) or Samsung 850 EVO with 250 GB vs Micron M600 with 256 GB (both for $160) . I know it's a small difference but this is my first experience with an SSD so I just want to make sure I make the right decision. I'll be putting the OS on the SSD so what capacity do you recommend? Thank you.
