Samsung Cranks Mass Production Of QLC V-NAND For Consumer 4TB SSDs

Samsung is once again showing itself to be among the leaders in NAND storage technology by today announcing that it has started production of 4-bit QLC (quad-level cell) SATA SSDs. The new QLC SSDs leverage 64-layer 1Tb V-NAND that retains the performance levels afforded by current 3-bit SSD offerings.

This QLC V-NAND will initially be used in mainstream consumer applications, which means that we're looking at SSDs with a SATA interface. Sequential read and write speeds are pegged at 540MB/sec and 520MB/sec respectively, and the SSDs will be available in a 2.5-inch form-factor for desktops and laptops. The company does note, however, that M.2 NVMe enterprise SSDs using QLC V-NAND will begin mass production later this year.

“Samsung’s new 4-bit SATA SSD will herald a massive move to terabyte-SSDs for consumers,” said Jaesoo Han, Executive VP of Memory Sales and Marketing for Samsung Electronics. “As we expand our lineup across consumer segments and to the enterprise, 4-bit terabyte-SSD products will rapidly spread throughout the entire market.”

Samsung says that its consumer SATA SSD offerings will be available in 1TB, 2TB, and 4TB capacities, which will be a boon to those looking for copious amounts of fast storage. In addition, the company says that QLC V-NAND will enable it to efficiently produce affordable 128GB microSD cards for smartphones.

At this time, Samsung has not disclosed a shipping window or pricing for these new SATA SSDs.
