Samsung is extending their 850 EVO and Pro lineups to include 2TB versions of the popular SSDs thanks to the use of 3D-VNAND; three bit memory on the EVO and two bit on the Pro.  They are rated at the same speeds as their 500GB and above counterparts and The SSD Review had a chance to test that. Interestingly they did indeed find performance differences between the 1TB and 2TB model of the same design, which you can check out in the full review.  Their results were not quite the same as Al's review which was just posted, you should compare the two reviews as well as the systems used for theories on why that is.  You can expect to pay ~$1000 for the 850 Pro 2TB and ~$800 for the 850 EVO 2TB.

"If you look back over the past several years, there have always been three constants that needed to be addressed in order for SSDs to become a viable consumer solution to storage; value, reliability and capacity. One of our first SSD reviews was on an MTron 32GB SSD with a whopping price tag of more than $1500…and they sold!"
