Hi All I have recently upgraded all the components of my pc. The old parts i have used to build a PC for someone except i am using a pretty old Sata HDD (the old system ran perfectly well for the age and components). Upon completing build for this 'new' build i've noticed that opening files, running files, opening browser etc takes a while longer than expected. Given that all the components were the same and the hard drive is the only 'old' part would i be correct in thinking that the HDD is the issue? Can the speed of an HDD significantly cause performance issues?
