The Bottom Line Storage-hungry users, especially tech-savvy ones, will find the Seagate Barracuda XT a great balance of storage space, backward compatibility, and speedy performance. Similar to the original, the Momentus XT (second generation) makes an excellent host drive for any computer, both laptops and desktops. It offers great value in terms of performance and cost, especially when compared to SDDs. The Samsung 840 Pro lives up to its name: it's a top-notch solid-state drive for professionals with a price to match. WD VelociRaptor WD1000DHTZ makes an excellent storage solution for housing a large amount of data that's frequently accessed and manipulated. Fast, user-friendly, and affordable, the WD Black 2 Dual Drive is an easy recommendation as a replacement drive for any standard laptop or desktop computer.
