When was the last time you checked this? SDD prices have skyrocketed back up in the past ~3-5 months as Samsung and SK have reduced production to halt losses. Prices are now back to where they were ~12 months ago. At least in Europe.
i bought a 2TB SSD for about that much in europe just two months ago. and i just checked the prices, they are still at that level. obviously you can find more expensive ones too
