Though Samsung has high hopes for this new 4TB SSD. Performance is on a par with the older 850 Evo drives at a 540MB/s read speed and 520MB/s write. Samsung, however, thinks that it's solved the puzzle when it comes to making 4-bit QLC drives a reality by using 3-bit controller and its own TurboWrite technology.
Samsung is ramping up its efforts with solid state drives, beginning mass production of the industry's first commercial 4-bit quad-level cell (QLC) 4TB SSD.
The company says that when data stored within a memory cell is bumped up from three bits to four, maintaining optimum performance and speed becomes "considerably more hard".
Not only that, but that 1Tb V-NAND chip means that Samsung will be able to "efficiently produce a 128GB memory card for smartphones", so it certainly sounds like the company's plans for QLC could lead to big changes for storage in general. At least there's plenty of competition in the QLC space, so hopefully we'll be pleasantly surprised by the price.
