An SSD upgrade is still the single best thing you can do for your PC
By Jeandre de Beer / Pc World
I can't tell you exactly how much your PC will speed up with an SSD. But I can tell you it will be a lot.
John is "considering upgrading to a SSD."
He wants to know "how much faster would it really be?"
I can't tell give you exact numbers because I don't know either your computer or what SSD you'll buy. But I can tell you this: The hard drive, with its mechanical moving parts, is almost certainly the biggest bottleneck in your PC. (If it isn't, you've got something seriously wrong–probably in the software.) Replace that hard drive with an SSD, and the bottleneck disappears.
