The 850 EVO mSATA comes in a small white box. While there aren't a lot of details on the front, the back of the box shows some of the drive's features including 3D V-NAND technology and a 3 year warranty. Inside, you'll find the SSD as well as a small guide with a warranty statement summary and user manual.
Physical Features:
The 850 EVO mSATA follows the JEDEC MO-300 standard for mSATA SSDs. It measures a mere 50.8 x 29.8 x 3.6 mm and is about one quarter the size of a standard 2.5-inch drive. The 850 EVO mSATA also has a 52-pin mSATA connector which supports data transfer rates up to 6 Gb/s.
The 120GB version of the 850 EVO mSATA uses Samsung's MGX (S4LN062X01-Y030) controller chip. There still isn't a lot of information available regarding this controller but from what we can gather, it is very similar to the MEX (S4LN045X01-8030) controller found in the 850 PRO and the 1TB version of the 850 EVO. The biggest difference is that instead of three cores, the MGX has only two.
For the 120GB version of the 850 EVO mSATA, Samsung used their own 3-bit, 32-layer 3D V-NAND flash chips. Looking at the pictures above, you can see that there are two 64GB NAND flash packages on the top of the PCB. The drive also has a single 512GB LPDDR3 DRAM memory chip that is used for caching.
