Samsung 850 EVO 500GB SSD, $140 | 250GB, $90

An SSD is the best upgrade you can give your older computer, and Samsung’s 850 EVO line is the most popular one there is. A worldwide NAND shortage has reversed the previously inexorable downward price trend on these things over the past year or so, but today on Amazon, you can get a 500GB drive for $140, or 250GB for $90, the best prices Amazon’s listed in 2017.
