vNAND Gets a little TLC
We reported last week on Samsungs 850 Pro SSD with their new vNAND technology which allows for greater chip density, performance and lower power consumption. Now it Looks like Samsumg is preparing vNAND which uses TLC flash, much like Samsungs Evo Series SSDs. Is a Samsung 850 Evo SSD incoming?
For those who do not know the difference between TLC and MLC NAND, let me explain;
TLC (triple-level cell) flash is a higher density flash which stores 3 bits of information in each cell, which is 1 bit more than the MLC (multi-level cell) flash used in most of Samsungs other SSDs. This gain in storage density is offset by lower write speeds and durability of each individual cell, but these problems can be offset by giving the flash the 3D treatment as vNAND will simultaneously increase the write speeds and the durability of the flash. This makes a 3D, or vertical, TLC Flash highly desirable as its traditional disadvantages are offset by this new technology.
What does this mean to us? It means that Samsung can cram more storage space onto less flash chips without lower write speeds and less durability, which means that they can produce a fast reliable SSD for cheaper than their current 850 Pro and perhaps release a, let’s call it a 850 EVO SSD based on TLC vNAND for a reduced price.
Samsung now have everything they need to not just make the most advanced SSDs on the market, but also potentially the cheapest. So we look forward to seeing what Samsung have in store for us in the coming months.
