There's no doubt about it: one of the best ways to boost your computer's performance, is to upgrade your hard drive to a cutting edge solid state drive (SSD).
With no mechanical moving parts, no spinning platters, and just really fast flash memory, SSDs can instantly transform a sluggish computer into one with a whole new lease on life. Of course, this is due to the storage subsystem being the slowest part of a computer system. Your PC's CPU cache and main system memory are significantly faster than hard drives, so the CPU will always attempt to look up data in those two areas before resorting to hitting the hard drive.
With SSDs, having access times far superior to hard drives across their entire capacity range, they are must have for those craving the ultimate in performance. Unfortunately, they're still quite pricey. The good thing is that prices are falling swiftly.
The question of the day is: Have you upgraded to a SSD yet?
If so, which one?
