Samsung has announced a pair of high-capacity SSDs based on its 3D NAND (also known as V-NAND) technology — the 850 EVO and the 850 Pro.
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 SSds are packed 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 support the 2 TB format. There are four 20 nanometer-class 4Gb LPDDR3 DRAM chips inside it also.

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.Performance specs on the two drives haven’t been disclosed yet, but we’d expect the 850 Pro to be moderately faster than the 850 EVO, which uses TLC NAND and an SLC cache buffer to boost overall performance.It should be a nice addition to the 850 PRO series, especially with the rise of 4K video and the extra storage it requires.

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.
We will be uploading a full review of the new models soon.
