Introduction, Specifications and Packaging
Following the same pattern that Samsung led with the 840 Pro and 840 EVO, history has repeated itself with the 850 Pro and 850 EVO. With the 850 EVO launching late last year and being quite successful, it was only a matter of time before Samsung expanded past the 2.5" form factor for this popular SSD. Today is that day:
Today we will be looking at the MSATA and M.2 form factors. To clarify, the M.2 units are still using a SATA controller and connection, and must therefore be installed in a system capable of linking SATA lanes to its M.2 port. As both products are SATA, the DRAM cache based RAPID mode included with their Magician value added software is also available for these models. We won't be using RAPID for this review, but we did take a look at it in a prior article.
Given that 850 EVOs use VNAND - a vastly different technology than the planar NAND used in the 840 EVO, we suspect it is not subject to the same flash cell drift related issues (hopefully to be corrected soon) in the 840 EVO. Only time will tell for sure on that front, but we have not see any of those issues present in 850 EVO models since their launch.

Samsung sampled us the M.2 SATA in 120GB and 500GB, and the MSATA in 120GB and 1TB. Since both are SATA-based, these are only physical packaging differences. The die counts are the same as the 2.5" desktop counterparts. While the pair of 120GB models should be essentially identical, we'll throw both in with the results to validate the slight differences in stated specs below.

[H]ard|OCP just wrapped up a review of the 120GB Samsung 840, using their own ARM Cortex R4 based MDX controller and TLC memory for storage. They compare the speed of this drive to the 256GB 840 Pro, Kingston's V300 120GB and the Intel 335 240GB to contrast the difference the type of NAND used can make to performance. This is especially evident on the write and latency benchmarks, which fall well behind the competition. From [H]'s testing it is apparent that TLC memory is very vulnerable to reduction in size, the reduced channels really hurt performance and put the 120GB model far behind the larger sized 840s which they have tested with much better results.
"The 120GB Samsung 840 Series SSD features the powerful 8-channel MDX controller and TLC NAND. While this value SSD comes at a very good price, it also features much lower speeds than its larger capacity brethren. We put this value SSD through our suite of steady state tests to see if it can pass muster."

OWC appeared on the SSD scene in partnership with Apple, though they sold drives to PC users as well. Their current generation uses SandForce's Release Candidate firmware for the SF-2281 controller as opposed to OCZ's official firmware that is present in the Vertex 3 SSDs. That is not the only difference, OCZ rolled their own PCB while OWC went with a design that caused a few raised eyebrows at AnandTech. Read their full review to see how the performance evened out.
"I still don't get how OWC managed to beat OCZ to market last year with the Mercury Extreme SSD. The Vertex LE was supposed to be the first SF-1500 based SSD on the market, but as I mentioned in our review of OWC's offering - readers had drives in hand days before the Vertex LE even started shipping.
I don't believe the same was true this time around. The Vertex 3 was the first SF-2200 based SSD available for purchase online, but OWC was still a close second. Despite multiple SandForce partners announcing drives based on the controller, only OCZ and OWC are shipping SSDs with SandForce's SF-2200 inside."
