Samsung's mSATA SSD is a super fast solid-state drive, shrunk down to mSATA size. Here's PC Advisor's Samsung 840 EVO mSATA 500 GB review and lab tests.

We love speed… and after reviewing the Samsung 840 Pro , we were chomping at the bit to get the 840 EVO in the lab.  Not only does the newer EVO model use newer 19nm 3-bit Triple-Level Cell vs that of 2-bit MLC found in the 840 Pro, but it also features a much more attractive price-point and an...

The Samsung 840 Pro landed on our Best of the Best list when it was launched in December 2012, and it has remained at the top of the SSD pile ever since, thanks to its blistering speed, impeccable pedigree, and superb software.

Ridiculously fast; effective caching; every capacity

Only three-year warranty

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

Excellent price on SSD. Overstock's website is easy and intuitive to use. Shipping was expedient.

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

There are three important things you should keep in mind when buying a solid-state drive: capacity, performance, and pricing. And the new Samsung 840 Evo makes things easy by offering them all, and more.

The Samsung 840 Evo solid-state drive offers overall excellent performance; top storage space; and useful bundled software; at low cost

The three-year warranty is relatively short; and the drive's sequential read speed could be a tad better

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.

The Samsung 840 EVO (500GB) ($259) internal solid-state drive (SSD), the follow-up to the company's Samsung 840 Series 250GB($378.89 at Amazon)(Opens in a new window), retains the TLC flash memory that debuted in its predecessor, but adds functionality to boost performance. The result is one of the best SSDs we've ever seen, with a dynamite price/performance ratio. Appropriately, the "EVO" suffix stands for "evolution"—this is the second drive to use triple-level-cell (TLC) NAND and it includes a write-performance-boosting feature that addresses one of the principle complaints regarding the flash memory type. Samsung is one of a handful of companies using TLC NAND; most drives today use multi-level-cell (MLC) flash memory. The difference between the two is the number of bits that are stored in each memory cell. Traditional MLC stores two bits; TLC flash, as the name implies, stores three. The shift to TLC NAND has been slow, despite the additional storage it offers. TLC NAND is ...

Whether you're a regular user or even an enthusiast, the Samsung 840 EVO (500GB) has the best price/performance ratio of any internal solid-state drive (SSD) you can buy today.

Costs just over 50 cents per GB; Performs like a standard multi-layer-cell (MLC) drive

Its triple-level-cell (TLC) NAND isn't suitable for all workloads or scenarios
