Today Samsung has announced a pair of 2TB solid-state drives, the 850 PRO and 850 EVO, based on the company's 3D vertical-NAND (V-NAND) technology, the first 2TB SATA SSD's to the market. 

 Based on the same three-dimensional cell layout as the company's other high-capacity drives, both the 850 PRO and 850 EVO 2TB flavours feature a 7mm 2.5" aluminium casing housing 128 individual 32-layer 128Gb 3D V-NAND flash chips. The drives boast an upgraded MHX controller with support for the impressive 2TB capacity, along with 2GB of LPDDR3 cache memory in four 4GB 20nm chips.

Of course both drives are targeted at slightly different markets, the 850 EVO SSD line is designed more for everyday computing, consumer in mind while the 850 PRO SSD Line is targeted towards the coparate/enterprise customer. They differer in the sense the EVO line offers a 5 Year warranty or 150 terabytes-written warranty while the 850 PRO offfers 10 years or 300 terabytes-written. The 850 EVO boasts 540MB/s and 520MB/s sequential read and write speeds respectively, while the 850 PRO raises the read speed slightly to 550MB/s.

 The UK pricing has been confirmed at - 850 EVO £636.99 and 850 PRO £749.99
