Samsung starts mass production of first 4-bit SSDs for consumers

"As we expand our lineup across consumer segments and to the enterprise, 4-bit terabyte-SSD products will rapidly spread throughout the entire market".

QLC tech, which allows one cell to hold four bits of data, has been available in enterprise storage from Toshiba for a little while. Drive capacity is increased through the use of 32 chips, all based on 64-layer 4th generation 1Tb V-NAND technology.

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".

Snapchat drops daily users for first time after controversial redesign
Saudi Arabia's Prince Alwaleed bin Talal has bought a 2.3% stake in Snap - the company behind Snapchat - for $250m (£193m). Snap also has been redesigning its app to encourage users to interact with more of its ad-supported videos.

Samsung has announced it has put production of its first consumer QLC SSD into overdrive.

According to Jaesoo Han, the EVP of memory sales at Samsung Electronics, "Samsung's new 4-bit SATA SSD will herald a massive move to terabyte-SSDs for consumers".

While leading 4TB hard drives now cost $100, Samsung's existing 860 EVO 4TB SSD costs over $1,000.

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.
