| The Bottom Line | With very good performance and even better pricing, the SanDisk Extreme makes a great replacement drive for a standard laptop or desktop computer. | The Samsung 840 Pro lives up to its name: it's a top-notch solid-state drive for professionals with a price to match. | If you're moving up from a hard drive, the SanDisk Ultra Plus is totally worth its price. | The Samsung 840 series is an excellent entry-level solid-state drive for budget and general users, but not really a good buy for advanced or professional users. | The OCZ Vector Series SSD would make a great investment for those moving on from using a hard drive as the main drive of their system. | Basic specs |
