Samsung 850 EVO 1TB SSD

Samsung abandoned the black packaging with the 850 EVO. The minimal retail package design keeps it simple on the front, but does highlight the 3D V-NAND technology.

The rear of the retail package gives us some basic information about the 850 EVO, shows the five-year warranty, and has a massive list of regulatory symbols.

Inside of the package, we found the 850 EVO SSD, a software disk with Magician and Data Migration, and two paper manuals.

This is the first Samsung SSD to abandon the red / orange square at the bottom of the drive. This image almost looks like a black and white picture, but it's not.

The back of the drive gives us the model number, serial number, and PSID for encryption.

The 850 EVO uses a 7mm case design, so it will work in notebooks that require the smaller z-height.

Inside, we found a small PCB with eight NAND flash packages, a controller, and DRAM package. All of the major components are designed and built by Samsung.

The low amount of components needed for the 850 EVO almost amazes me.

The Samsung MEX controller used on the 1TB 850 EVO was also used on the 850 Pro, and 840 EVO products. This is an eight-channel design that is very powerful, but consumes very little power.

The 850 EVO only has one DRAM package to buffer data.

This is our first look at Samsung's new 32-layer, 3-bit per cell 3D V-NAND.
