Last week Samsung announced the new 840 Evo SSD series to replace the existing 840 series. The write speeds should be significantly higher, but the affordable price remains the same. We tested the entire series consisting of 120 GB, 250 GB, 500 GB, 750 GB and 1 TB models.

There is no doubt that when Samsung look to take over a market they can get things really right and there is no better example than how well their Galaxy range of smartphones is doing in an ever more crowded mobile market.

And here we were, staring multiple SandForce drives in the face, thinking solid-state innovation had ground to a halt. How wrong we were. Boffins at some of the biggest names in the industry have proven that there's plenty of room for improvement, with Intel introducing a new level of consistency...

I'm continually amazed by Samsung's rise to power in the SSD space. If you compare their market dominating products today to what we were reviewing from Samsung just a few years ago you'd assume they came from a different company.

The 1TB 840 EVO is the drive we've been waiting for and could cement Samsung at the top of the SSD tech tree.

Excellent performance; 930GB of usable storage; 4K random write figure very impressive; Good price

RAPID mode did not offer a performance boost

The Samsung 840 EVO 750GB is a triumph in solid-state technology, combining for the first time vast capacity by flash standards, with lightning performance, and at an approachable price.

TRIM Performance: While SSDs offer many benefits, there are some downsides to using flash memory. One of the biggest issues people run into is performance degradation. Over time, an SSD will run out of fresh blocks and will have to write over data the file system has marked as deleted.

Available in 120GB; 250GB; 500GB; 750GB and 1TB capacities; Features RAPID mode and TurboWrite technology; Excellent sequential read and write speeds; Very good random read and write performance; Performs equally well with compressible and incompressible data; Good looking; ultra-slim design; SATA...

Samsung's 3-bit MLC NAND is not as durable as 2-bit MLC NAND

Picked this up from Playtech for $275. Unboxing it at first was strange, seemed as if its packaging weighed more than the drive itself, meaning the drive is impossibly light, at first I thought it was just an aluminum shell. However, it's nice.

Nothing wrong with the drive, and frankly for the quality and size/money POV, Samsung has the consumer SSD market sewn up with very few exceptions.

Outstanding combination of features, innovation, performance, and price.

Slimline design; RAPID Mode for jaw-dropping performance boost; free Data Migration utility; user-friendly Magician software; Outstanding value
