As solid-state storage goes, more is better—and Samsung is providing a lot more today. The company has doubled the capacity of its biggest 850 Pro and 850 EVO SSDs to 2TB, making them the first such consumer-oriented drives available.
As with the smaller versions of the 850 Pro and EVO, these 2TB drives use Samsung's 3D V-NAND stacked-flash technology. The 850 Pro uses MLC flash, while the EVO sticks with TLC. The biggest change is in the controller chip: both drives use a new Samsung MHX controller to handle the extra flash dies, according to PCPerspective's review. Performance for the new drives appears to track pretty closely with their 1TB counterparts.
Samsung backs the 850 EVO with a five-year warranty, while Pro buyers are treated to ten years of support. As one would expect, that much space doesn't come cheap: PCPer says the 2TB EVO lists for $800, while the 2TB Pro runs a cool $1000. We've reached out to Samsung for more information, and we'll update this post as we learn more.
