The Bottom Line The Momentus XT is an excellent replacement for traditional laptop hard drives. It offers large capacities and SSD-like performance at a fraction of the cost. 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. If you're looking for SSD-like performance at just a fraction of the cost, the Seagate Laptop Thin SSHD offers some gratification. 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.
