Critic Reviews


And Samsung plans to ask a price that millions of customers have already paid for vanilla 840s. With the addition of 750 GB and 1 TB models, the company's mainstream SSD family is pretty darned complete. Left with little else to ask for from an SSD, we're pleased to confer the Tom's Hardware Smart Buy award on Samsung's 840 EVO.

The Samsung 840 Evo entry-level SSD provides consumers with a very low $/GB option that still delivers more robust throughput across the board than almost all of the competition.

To say that I really like the EVO is an understatement. If Samsung can keep quantities of the 840 EVO flowing, and keep prices at or below its MSRP, it'll be a real winner and probably my pick for best mainstream SSD.
