I have a 2014 Samsung Ativ 9 lite. It has an msata ssd in it which houses the operating system and the 3 programs I use (chrome, office suite, and minecraft). Even with my mom's 2012 hp, i can browse the web and even play some mc without lag. On this laptop, i can't even watch a 720p video on youtube without it lagging and I can't play mc without turning everything to extremely low settings. I've been in IT for a couple years and don't understand why it's doing this. The only thing on the hard drive are the OS and the 3 programs.
Specs: 1.4ghz quad core cpu
4gb ram
128gb msata ssd
13" screen
