The Bottom Line So far, the Crucial m4 offers the best value among SSDs. Though it's not the fastest, it's by far the most affordable among its peers. The Samsung 840 Pro lives up to its name: it's a top-notch solid-state drive for professionals with a price to match. The Clickfree C6 would make an excellent portable storage and backup drive for any Windows user.
