Samsung 850 EVO M.2 SATA SSD Review (120GB/500GB) on The SSD Review| A few months ago we reviewed the the little brother to the Samsung 850 Pro, the Samsung 850 EVO in its SATA III 2.5’’ form factor. Now it’s time for the spotlight to shift to a new form factor, M.2. Just as with the 2.5″ model. Four months ago Samsung introduced the world to TLC V-NAND in the form of. It did well in our tests and showed that 3D NAND technology essentially brings TLC NAND to the level where planar MLC NAND stands today. The initial launch only included the most popular form factor in 2.5', but did not address the upgrade market where mSATA and M.2 are constantly growing in popularity. With today's release, Samsung is expanding the 850 EVO lineup with M.2 and mSATA models. The move isn't really surprising because Samsung released a bit over a year ago and when the 850 EVO was originally launched we were told that mSATA and M.2 models would follow later. The addition of M.2 is new to Samsung's retail lineup, but it makes a lot of sense given that many PC OEMs have switched from mSATA to M.2, and ultimately M.2 will be replacing mSATA in full. Architecturally the mSATA and M.2 models are not any different from their 2.5' sibling. The heart of the drives is still Samsung's own MGX controller (excluding the 1TB model, which is powered by the older MEX controller) and the NAND is 32-layer 128Gbit TLC (3-bit per cell) V-NAND that is manufactured using 40nm lithography. TurboWrite (Samsung's pseudo-SLC caching) is also included and the cache sizes have remained unchanged from the 2.5' model. DevSleep and TCG Opal 2.0 (eDrive) are both supported too and endurance comes in at a respectable 75TB for 120GB/250GB and 150TB for 500GB/1TB models. Given the similarity with the 2.5' model, I strongly suggest that you read for a full scope of TurboWrite, TLC V-NAND and other tidbits as I won't be covering those in detail in this review. • - Tuesday, March 31, 2015 - One thing you should probably do in M.2 SSD reviews is include how the drives are keyed, preferably in one of the tables. This is important since the M.2 interface is actually 4 semi compatible 'standards' (see As a result not all M.2 SSDs will fit in all M.2 slots. This one appears to be both B and M keyed so I think it should be pretty universal, but as an example the Samsung XP941 is only M keyed and thus will not work in the HP Stream Mini's B keyed SSD slot.

(Did whoever came up with M.2 make a crappy standard that will cause lots of customer support calls and RMA's when consumers M.2 drives don't work with their M.2 equipped computers? Yes they did.).
