Samsung has just announced that the company has begun the mass production of the industry’s first 4-bit 4TB SATA SSD for consumers. Based on 1-terabit V-NAND with enhanced performance equivalent to the company’s 3-bit design, Samsung’s QLC SSD is expected to bring a new level of efficiency to consumer SSDs.
The company aims to rapidly spread its proprietary 4-bit SATA SSD 4-bit terabyte-SSD offerings throughout the entire market. What’s more, with its new 1TB 4-bit V-NAND chip, Samsung will be able to efficiently produce a 128GB memory card for smartphones that will lead the charge toward higher capacities for high-performance memory storage.
Typically, as data stored within a memory cell increases from three bits to four, the chip capacity per unit area would rise and the electrical charge (used to determine information from a sensor) would decrease by as much as 50 percent, making it considerably more difficult to maintain a device’s desired performance and speed.
However, Samsung’s 4-bit 4TB QLC SATA SSD maintains its performance levels at the same level as a 3-bit SSD, by using a 3-bit SSD controller and TurboWrite technology, while increasing drive capacity through the use of 32 chips, all based on 64-layer fourth-generation 1TB V-NAND. Plus, the 4-bit QLC SSD will be able to deliver a sequential read and write speeds of 540 MB/s and 520 MB/s respectively.
Samsung also plans to introduce 1TB and 2TB models later this year in the widely used 2.5-inch form factor while all units will be backed by a three-year warranty. Additionally, the company expects to provide M.2 NVMe SSDs for the enterprise and begin mass production of 4-bit fifth-generation V-NAND.
This move will considerably expand the company’s SSD lineup to meet the growing demand for faster and more reliable storage solutions across a wide span of applications. You may also recall that Samsung was the first to unveil a 30TB SSD alongside the world’s largest enterprise 100TB SSD not that long ago.
