Samsung starts producing high-capacity 4-bit SSD

08 August 2018

Samsung claims its drive will be the "industry's first 4-bit consumer SSD", but we'll have to see about that. Buyers will get a 3 year warranty. Samsung says its 4-bit quad-level cells (QLC) drives will have the same or better performance as 3-bit SSDs thanks to a 3-bit controller and "TurboWrite" technology. At the time, it ensured consumers that the new memory solutions would allow for the creation of solid state drives (SSDs) with significantly increased capacity.

This makes it considerably more hard to maintain a device's desired performance and speed. Making use of the latest 4-bit cell to pack even more data into a tiny footprint, the Samsung SATA drive will feature a 4TB capacity and reach speeds of up to 540MB/s read and 520MB/s write. Pricing and exact availability have yet to be announced. But Samsung says its upcoming 4-bit 4TB QLC SSD boasts the same performance as a 3-bit SSD.

The new 4 TB drive is expected to be joined by 4-bit 1 TB, 2 TB and 4 TB 2.5-inch variants later in the year, with enterprise M.2 NVMe variants also in the pipe.

While leading 4TB hard drives now cost $100, Samsung's existing 860 EVO 4TB SSD costs over $1,000. Once this has flooded the market, Samsung promises that 1TB SSDs will become much more affordable as a result.

"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.

In addition to high-capacity SSDs, Samsung also revealed that with its new chip, it 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". At least there's plenty of competition in the QLC space, so hopefully we'll be pleasantly surprised by the price.
