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!"

Introduction, Specifications and Packaging
Where are all the 2TB SSDs? It's a question we've been hearing since they started to go mainstream seven years ago. While we have seen a few come along on the enterprise side as far back as 2011, those were prohibitively large, expensive, and out of reach of most consumers. Part of the problem initially was one of packaging. Flash dies simply were not of sufficient data capacity (and could not be stacked in sufficient quantities) as to reach 2TB in a consumer friendly form factor. We have been getting close lately, with many consumer focused 2.5" SATA products reaching 1TB, but things stagnated there for a bit. Samsung launched their 850 EVO and Pro in capacities up to 1TB, with plenty of additional space inside the 2.5" housing, so it stood to reason that the packaging limit was no longer an issue, so why did they keep waiting?
The first answer is one of market demand. When SSDs were pushing $1/GB, the thought of a 2TB SSD was great right up to the point where you did the math and realized it would cost more than a typical enthusiast-grade PC. That was just a tough pill to swallow, and market projections showed it would take more work to produce and market the additional SKU than it would make back in profits.
The second answer is one of horsepower. No, this isn't so much a car analogy as it is simple physics. 1TB SSDs had previously been pushing the limits of controller capabilities of flash and RAM addressing, as well as handling Flash Translation Layer lookups as well as garbage collection and other duties. This means that doubling a given model SSD capacity is not as simple as doubling the amount of flash attached to the controller - that controller must be able to effectively handle twice the load.
With all of that said, it looks like we can finally stop asking for those 2TB consumer SSDs, because Samsung has decided to be the first to push into this space:
Today we will take a look at the freshly launched 2TB version of the Samsung 850 EVO and 850 Pro. We will put these through the same tests performed on the smaller capacity models. Our hope is to verify that the necessary changes Samsung made to the controller are sufficient to keep performance scaling or at least on-par with the 1TB and smaller models of the same product lines.

Tagged: hybrid hdd, cache, Seagate, 2TB
Benchmarking cached HDDs can be a difficult task as they are specifically designed to cache commonly used data which results in two very different speeds for data access, the 8GB SSD and the actual HDD. The Tech Report recently met this challenge when benchmarking Seagate's first 3.5" desktop cached drive with 8GB of flash and 2TB of platter storage. When contrasting it to some of the higher end HDDs available it became apparent that the more expensive WD Black 4TB was a faster drive but as it does cost more per gigabyte it might not be the best choice for every purpose. Check out the review to see if this hybrid device is a better choice than buying both a small sized SSD and a large HDD for your own usage.
"Seagate's hybrid tech has finally been deployed in a desktop drive. The Desktop SSHD combines an 8GB flash cache with 2TB of mechanical storage. We take a closer look at how that combo holds up against standard hard drives and SSDs."
