"As we expand our lineup across consumer segments and to the enterprise, 4-bit terabyte-SSD products will rapidly spread throughout the entire market". 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. So even if you don't need a 4TB hard drive, the technology will lead to updated storage solutions for mobile devices as well (though 512GB smartphones might make memory cards obsolete). The so-called QLC quad-level cells pack more memory into the same space as previous 3-bit cells, while operating at the same speeds.

When data stored inside a memory cell increases from three bits to four, the chip capacity per unit area rises and the electrical charge that's used to determine information from a sensor decreases by up to 50 percent.
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.More news: Carrie Underwood Is, In Fact, Pregnant
That means the new drive family will be about to reach sequential read speeds of 540MB/s and sequential write speeds of 520MB/s.
Jaesoo Han, Executive VP of Memory Sales and Marketing at Samsung, said: "Samsung's new 4-bit SATA SSD will herald a massive move to terabyte-SSDs for consumers". Plus, each of the drives will come with three year warranties. The company's new 4TB QLC SSD is very fast and, though Samsung didn't share exact pricing yet, it's aimed primarily at consumers, not professionals. We now have no indication on pricing.More news: Saudi Arabia-Canada spat hits 16,000 students as the Kingdom suspends scholarships
Which all sounds rather nice, so long as Samsung can keep the prices of its new 4-bit tech to a minimum.
