Crucial MX300 2TB
http://www.crucial.com/usa/en/ct2050mx300ssd1
Posting this because I know how poor selection of 2TB drives there is. Checking tests, it's quite a lot slower than Samsung 850 Pro or Evo, but also costs another 100€ less. It's still SSD, so it'll be way faster than HDD and is made by Crucial which has been very reliable so far. This one also comes with 3D NAND, rated at 400 TBW. And for 500€, it's not that bad of an option actually.
