Samsung produces high-capacity 4-bit solid-state drive (SSD)

SEOUL: Setting the stage for rolling out advanced memory technology to meet the growing demand for faster, more reliable performance across a wide span of applications, Samsung on Tuesday said it began mass producing the industry’s first 4-bit SATA solid-state drive (SSD) for consumers.
The South Korean tech giant said it would launch several 4-bit consumer SSDs later this year with 1TB (terabyte), 2TB, and 4TB capacities in the widely used 2.5-inch form factor. The new 4-bit quad-level cell (QLC) SSD is expected to bring a new level of efficiency to consumer SSDs.

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

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 per cent, making it considerably more difficult to maintain a device’s desired performance and speed.
