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.
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 1TB 850 EVO's PCB was. Instead of using a regular size PCB, Samsung has placed a 1.8" form factor PCB inside of a 2.5" case.
The 1TB version of the 850 EVO uses Samsung's own S4LN045X01-8030 controller. Developed entirely in house, this proprietary, triple-core MEX controller excels at multi-tasking. Based on an ARM Cortex R4 (400MHz) controller, its three CPU cores can execute multiple instructions such as reading data, writing data and optimization.
For the 1TB 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 are four 128GB NAND flash packages on either side of the PCB. The drive also has a single 1GB LPDDR2 DRAM memory chip that is used for caching.
