I have the Samsung 840 120gb, and I noticed Newegg has the 120gb EVO on Shell Shocker so I came here to compare them. While I am happy with my 840 the question from this comparison I have is IF the EVO has faster 4k Random Read, and Quicker 4k Random Access Time, then how is it that the 840 Windows Boot time is 7.6s vs the EVO's 9.5s? Doesn't make sense to me, anyone else?
