Samsung looked to usher in the consumer adoption of solid state drives (SSDs) back in 2013 with the launch of its speedy EVO series. It continues to forge ahead with its high-capacity vision for consumer-oriented, flash memory storage solutions with the addition of a pair of 2TB SSDs to its lineup.

The newest members of Samsung's SSD family are powered by the company's proprietary 3D Vertical NAND (V-NAND) technology, which it first unveiled in 2013. This brings the total range of products in its SSD lineup to 20, ranging in capacity from 120 GB up to the whopping new 2 TB options.

The drives are housed in the same 7 mm, 2.5-in aluminum casing as previous models and comprise 32 layers of 128 GB 3D V-NAND flash chips and an improved MHX controller to better support the 2 TB format. Also inside are four 20 nanometer-class 4Gb LPDDR3 DRAM chips.

Samsung has launched two versions, the 2 TB 850 EVO and 2 TB 850 PRO. The PRO variants have traditionally promised slightly better read/write speeds and reliability. Though Samsung is yet to release technical details on the new drives, it is guaranteeing the PRO model for 10 years or 300 TB written, and the EVO model for five years or 150 TB written.

The 2 TB 850 EVO is expected to cost US$800 and the 2 TB 850 PRO $1,000. There's no official release date yet, but they will be available to buy in 50 countries. Samsung also says that it has plans to extend the 3D V-NAND SSD lineups to include mSATA and M.2 form factors.

While the entry level 120GB/128GB sizes have come down in price quite a bit and making it a much more viable option for many who have held off for years due to price, these much less common, much higher sizes, 1TB and above are still too much for many to replace traditional platter drives in these larger sizes.
EH
A lifetime of 150 or 300TB written seems like a lot, but that is only 75 or 150 full write passes, while the flash memory should be good for at least thousands of cycles. I would have thought that error correction and wear leveling were good enough to guarantee at least 10x the lifetime they are quoting.
