Samsung Announces 4TB QLC SSDs For Consumers
Today Samsung Electronics Co., Ltd., announced that it is mass-producing a 4-bit or quad-level cell (QLC) SATA SSD for consumers. The company states that this will result in a 4TB SATA SSD for the consumers market, an industry’s first using QLC.
The new 4-bit technology is based on Samsung’s 1Tb V-NAND. Moving from 3-bit to 4-bit is expected to bring greater efficiency while maintaining its performance. The company is claiming performance numbers of 540MB/s read and 520MB/s write and a 3-year warranty. The performance is in part due to using Samsung’s 3-bit SSD controller and TurboWrite Technology.
Samsung is also planning on adding 4-bit fifth-generation V-NAND technology to its M.2 NVMe SSDs geared toward the enterprise. This will expand the company’s SSD lineup while allowing it to better address the demand for faster, reliable performance across use cases in data centers, enterprise servers, and enterprise storage.
Samsung intends for the 4-bit consumer SSD to be available later this year in 1TB, 2TB and 4TB capacity in a 2.5” form factor.
