Just over a decade ago, Samsung announced the imminent arrival of the first laptops to come with 32 GB NAND flash storage. Now the company is set to shake up the storage tree again as it goes into mass production of the first consumer-level 4-bit, 4 TB SATA solid state drive, signaling a possible turning point for high capacity home storage.
“Samsung’s new 4-bit SATA SSD will herald a massive move to terabyte-SSDs for consumers,” said Samsung’s Jaesoo Han. “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 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 difficult.” But Samsung reckons that by using a 3-bit SSD controller, TurboWrite technology and making use of 32 fourth gen 64-layer V-NAND chips, the new 4 TB QLC SATA SSD doesn’t suffer such a performance drop.
