'As we expand our line-up across consumer segments and to the enterprise, 4-bit terabyte-SSD products will rapidly spread throughout the entire market. In 2010, it introduced its 2-bit multi-level cell with 512GB, while in 2012 it released the 3-bit triple-level cell which had 500GB storage but double the chip capacity of the previous model.

With the Flash Memory Summit in Santa Clara quickly approaching, Samsung has made a rather exciting announcement for those who pine for high-capacity SSDs. Performance is on a par with the older 850 Evo drives at a 540MB/s read speed and 520MB/s write.

Samsung claims its 4-bit SSDs maintain the same performance levels as its 3-bit equivalents, by using a 3-bit SSD controller and TurboWrite technology.

'Samsung's new 4-bit SATA SSD will herald a massive move to terabyte-SSDs for consumers, ' said Jaesoo Han, executive vice president of memory sales & marketing at Samsung Electronics.

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".

But Samsung is bringing QLC tech to consumers for the first time and will be offering up to four-terabyte (TB) SATA solid-state drives (SSD) in 2.5-inch form factor devices.

With its new 1 terabit 4-bit V-NAND chip, Samsung said it will also be able to efficiently produce a 128GB memory card for smartphones which will lead the charge toward higher capacities. Plus, each of the drives will come with three year warranties.

Samsung is also planning on adding 4-bit fifth-generation V-NAND technology to its M.2 NVMe SSDs geared toward the enterprise.

The Samsung 4TB 850 EVO SSD is now listed on with a £1,399.99 retail price (albeit discounted to £999.99 at present).
