Today I had issues with my computer. It would bluescreen on start up due to a memory managment issue and kernel security check failure. It was at a point where it would BSOD on windows install. When I plugged the HDD out it worked fine. I'm currently looking for a new one and I was wondering if there are any quality diffrences and real world speed between the WD blue and the Seagate barracuda guardian HDDs.
