The 990 PRO comes in a small black box. Along with a picture of the drive, the packaging advertises a number of its key features including its 2TB capacity, PCIE 4.0 NVMe interface, maximum read speed and 5 year warranty. Inside, you'll find the SSD as well as a small installation guide and warranty statement.

Physical Features:

The 990 PRO uses the 2280 form factor for M.2 (NGFF) SSDs. It measures 80 x 22 x 2.3 mm and tips the scales at a mere 9.0g. The drive also has an "M key" edge connector which provides PCIe SSDs with up to 4x lanes of bandwidth.

The 990 PRO is the first drive to utilize Samsung's "Pascal" controller. As usual, the company hasn't provided a lot of specifics regarding the controller's technical specs. What we do know, though, is that the Pascal has been manufactured using an extremely fine 8nm process and is designed with low-power architecture that increases low power mode. The controller also uses a nickel coating and a cutting-edge thermal control
algorithm to manage heat.

For the 2TB version of the 990 PRO, Samsung has used their own 7th-generation V-NAND flash chips. Looking at the pictures above, you can see that there are two 1TB NAND flash packages on the top of the PCB. The drive also has a single 2GB LPDDR4 DRAM memory chip that is used for caching.
