It’s been 10 years since Samsung first announced the 32 GB NAND flash storage for the first laptop. Can you imagine how the company is planning to mass produce the first consumer-level 4-bit, 4 TB SATA solid state drive? This is sure going to make a huge impact on the whole storage device industry and prove to be a turning point for high capacity local storage.
Samsung expects to develop Quad-level cell (QLC) flash storage technology to shake up the storage industry. The technology steps up the bit-per-cell capacity from the current three bits to four.
Samsung’s Jaesoo Han said –
Samsung’s new 4-bit SATA SSD will herald a massive move to terabyte-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.
The company explained that when data stored with a memory cell it is bumped up from three bits to four, maintaining optimum performance and speed becomes “considerably more difficult.” Instead, Samsung explained using a 3-bit SSD controller, TurboWrite technology and making use of 32 fourth gen 64-layer V-NAND chips, the latest 4 TB QLC SATA SSD will not see a drop in its performance level.
You will notice the sequential read speed is given as 540 MB/s, whereas sequential write as 520 MB/s, yet random read/write figures have not been revealed.
If you think this technology will rapidly bring a decline in the popularity of large capacity hard disk? We guess not! As the price of the latest HDD can be a deciding factor and Samsung is not revealing anything about it.
Though the production has started for the 4TB drive with 4-bit. but gradually 1 TB, 2 TB, and 4 TB 2.5-inch variants will begin by the end of this year with enterprise M.2 NVMe variants also in the pipe. Samsung is confident that its new 1-terabit 4-bit V-NAND chip will enable the company to produce large capacity memory for smartphones, too.
