The 850 EVO 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 5 year warranty. Inside, you'll find the SSD, warranty statement, installation guide and a CD containing the manual and Samsung's SSD Magician and Data Migration software.
Physical Features:
Like Samsung's previous SSDs, the 850 EVO is very well constructed. The drive's outer casing is made entirely out of aluminum and is very strong and lightweight. The 850 EVO also shares the same black color scheme found on the 850 PRO. However, instead of a red square, the one on the 850 EVO is grey.
Upon opening the case, I was a bit surprised to see how small the 850 EVO's PCB was. Instead of a regular size PCB, Samsung has placed a half-slim SATA SSD inside of a 2.5" case.
The 120GB version of the 850 EVO uses Samsung's new S4LN062X01-Y030 controller chip. At the moment, very little is known about this controller. The only thing we do know is that the MGX is designed for low capacity models and that it has been optimized for client PC usage patterns.
For the 120GB version of the SSD 850 EVO, Samsung used their own 3-bit, 32-layer 3D V-NAND flash chips. Looking at the pictures above, you can see that there is a single 128GB K90KGY8S7C NAND flash package on the top of the PCB. The drive also has a 256GB LPDDR2 DRAM memory chip that is used for caching.
