SEOUL, Korea \u2013 August 7, 2018 \u2013<\/span> Samsung Electronics Co., Ltd<\/strong>., the world leader in advanced memory technology, today announced that it has begun mass producing the industry\u2019s first 4-bit (QLC, quad-level cell) 4-terabyte (TB) SATA solid-state drive (SSD) for consumers.<\/p>\n

Based on 1-terabit (Tb)* V-NAND with outstanding performance equivalent to the company\u2019s 3-bit design, Samsung\u2019s QLC SSD is expected to bring a new level of efficiency to consumer SSDs.<\/p>\n

\u201cSamsung\u2019s new 4-bit SATA SSD will herald a massive move to terabyte-SSDs for consumers,\u201d said Jaesoo Han, executive vice president of memory sales & marketing at Samsung Electronics<\/strong>. \u201cAs we expand our lineup across consumer segments and to the enterprise, 4-bit terabyte-SSD products will rapidly spread throughout the entire market.\u201d<\/p>\n

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.<\/p>\n

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\u2019s desired performance and speed.<\/p>\n

However, Samsung\u2019s 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.<\/p>\n

The 4-bit QLC SSD enables a sequential read speed of 540 MB\/s and a sequential write speed of 520 MB\/s, and comes with a three-year warranty.
\nSamsung plans to introduce several 4-bit consumer SSDs later this year with 1TB, 2TB, and 4TB capacities in the widely used 2.5-inch form factor.<\/p>\n

Since introducing the 32-gigabyte (GB) 1-bit SSD in 2006, which ushered in the PC SSD era, to today\u2019s 4TB 4-bit SSD, Samsung continues to drive new thresholds for each multi-bit generation.**<\/p>\n

In addition, the company expects to provide M.2 NVMe SSDs for the enterprise this year and begin mass production of 4-bit fifth-generation V-NAND. This will considerably expand its SSD lineup to meet the growing demand for faster, more reliable performance across a wide span of applications, such as next generation data centers, enterprise servers, and enterprise storage.<\/p>\n\n\n\n\n\t\n\n\t\n\t\n\t\n\t
