Samsung 850 Evo 250GB review

Price when reviewed

Samsung’s newest drive – the 850 Evo – is cheaper than the 850 Pro, but still uses 3D V-NAND flash chips. The 850 Evo is produced with TLC rather than MLC memory, so cells store three bits of data rather than two – a move that increases storage density and reduces cost at the expense of performance.


That’s not to say the Evo is sluggish. It impressed in AS SSD, occasionally besting even the Samsung 850 Pro. Its IOMeter result of 5,270 is decent, too. In fact the Evo only faltered in ATTO. Its larger-file read speeds proved slow, and most of its write speeds were average.

The £110 Evo is the best mid-range drive we’ve seen, however, with better all-round performance available from the Samsung 850 Pro for only £28 more, we’d suggest you save a few more pennies and opt for that drive instead.
