| Bottom line | 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. | If the price is right, you don't need to look any further than the Samsung 830 series to upgrade your computer's internal storage to the best possible performance. |
