Samsung introduces Samsung 850 Pro SSDs with 3d v-nand flash




Samsung on Tuesday brought its first consumer SSDs with 3d-v-NAND memory market. Consumers with stacked flash memory drives come in variants of 128GB to 1TB market and mainly competes on performance.

The 850 Pro-Series SSD consists of diameter 2.5 “drives, as well as distinctive property of 3d-v-NAND flash memory. With this type of chips Samsung stacking multiple layers of memory cells on each other, which leads to more efficient designs. This makes, among other things Samsung memory can fabricate, which are cheaper on a 3Xnm process and produces less than technological obstacles, according to Samsung that the life of the chips is longer. 21nm or 19nm production of other flash chips. taking advantage

Due to the design of the cells, the 850 Pro drives have better performance than those of prior SSD on the basis of conventional flash memory, in spite of the use of a larger process, claiming Samsung, while also the power consumption would be reduced. The current 3D-v-NAND memory has a capacity of 128Gbit, but Samsung said to be able to enter into or to 1Tbit per chip. Capacity at constant process considerably

Moreover, for the first generation of 3D memory, last year for enterprise drives in production was still 24 layers stacked and Samsung knows the consumer models now stack. though 32 layers The 850 Pro Series is available from this month, with prices that would lie with those of the 840 Evo series in line. Shows the 850 Pro SSDs are faster than most SSDs, but not rapper than 840 Evo. First tests The longer life and extended warranty make the drives or for example workstations.
