The 2TB 850 SSD Pro and Evo drives are Samsung's newest and highest capacity retail offerings. They feature the same 7-millimeter, 2.5-inch aluminum form factor as their predecessors did, and are equipped with Samsung's advanced chip solutions, including 128 individual Samsung 32-layer 128Gb 3D V-NAND flash chips, an upgraded high-performance MHX controller that supports 2TB capacity, and four 20nm-class process technology-based 4Gb LPDDR3 DRAM chips.
"Samsung experienced surge in demand for 500GB and higher capacity SSDs with the introduction of our V-NAND SSDs. The release of the 2TB SSD is a strong driver into the era of multi-terabyte SSD solutions," said Un-Soo Kim, Senior Vice President of Branded Product Marketing, Memory Business at Samsung Electronics. "We will continue to expand our ultra-high performance and large density SSD product portfolio and provide a new computing experience to users around the globe."
These drives are desktop only at present, but according to Samsung there are plans for notebook versions as well.
Samsung guarantees the 2TB 850 Pro for 10 years or 300 terabytes written (TBW), and the 2TB 850 Evo for five years or 150 TBW.
Fast flash storage doesn't come cheap though, with the 2TB 850 Evo priced at $800, and the 2TB 850 Pro hitting $1,000.
