The 860 PRO comes in a small black and red box. While there aren't a lot of details on the front, the back of the box advertises some of the drive's key features including its V-NAND technology and 5 year warranty. Inside, you'll find the SSD as well as a small installation guide and warranty statement.
Physical Features:
Like Samsung's previous SSDs, the 860 PRO is very well constructed. The drive's outer casing is made entirely out of aluminum and is very strong and lightweight. The 860 PRO also shares the same black color scheme found on the 860 EVO. However, instead of a gray square, the one on the 860 PRO is red.
Upon opening the case, I was a bit surprised to see how small the 860 PRO's PCB was. Instead of a regular size PCB, Samsung has placed a half-slim SATA SSD inside of a 2.5" case.
Like the 860 EVO, the 860 PRO uses Samsung's new MJX controller. The company hasn't provided a lot of specifics regarding the controller's technical specs. However, they have stated that in addition it to providing faster communication with the host system, the MJX provides much wider compatibility with other devices. This includes improved queued trim which enhances Linux compatibility.
For the 512GB version of the 860 PRO, Samsung used their own 64-layer, 2-bit MLC V-NAND flash chips. Looking at the pictures above, you can see that there is a 256GB NAND flash package on either side of the PCB. The drive also has a single 512GB LPDDR4 DRAM memory chip that is used for caching.
