I have a laptop that had a standard 500gb HDD that was feeling a bit slow, so I decided to pick one of these up to replace it. After transferring the data from my old hard drive to the 840 EVO I opened up the computer and popped the new SSD in. The data transfer process was painless and simple, and as soon as I turned my laptop on the difference was obvious. Much faster booting up, waking from sleep is practically instant, everything is just snappier by a mile. And the software included gives me so much control over the performance of the drive, I am very happy with my purchase. If you're looking to perk up your computer without emptying your wallet, this is my first choice!
