The 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 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 Pro lives up to its name: it's a top-notch solid-state drive for professionals with a price to match.
