"As we expand our lineup across consumer segments and to the enterprise, 4-bit terabyte-SSD products will rapidly spread throughout the entire market".
Nearly all storage manufacturers are pushing higher in capacity, with Seagate unleashing a line of Barracuda SSDs earlier this year using 3-bit QLC chips.
With the Flash Memory Summit in Santa Clara quickly approaching, Samsung has made a rather exciting announcement for those who pine for high-capacity SSDs. This makes it hard to maintain desired performance and speed. The chips in use today are triple-level-cell (TLC) and store 3-bits per cell (64Gb per chip) and gave us cheaper 500GB drives while allowing for up to 4TB capacity using a lot of chips and therefore a high price.
As the chip capacity per unit area rises from 3 to 4-bit, electric charge can decrease by as much as 50 percent.
The 4-bit QLC SSD promises a sequential read speed of 540MB/s, and a sequential write speed of 520MB/s.
Executive vice president of memory sales & marketing at Samsung Electronics, Jaesoo Han explains that "Samsung's new 4-bit SATA SSD will herald a massive move to terabyte-SSDs for consumers". Samsung hasn't announced specific pricing, but 4-bit cells should narrow the gap a little.
And if you're anxious about reliability, know that these drives will have a pretty generous three-year warranty. Samsung said that its new SSDs have "outstanding performance" and are expected to bring a new level of efficiency to consumer SSDs.
For the enterprise, it's planning to begin mass production of the four-bit fifth-gen V-NAND M.2 NVMe SSDs later this year.
Not only that, but that 1Tb V-NAND chip means that Samsung will be able to "efficiently produce a 128GB memory card for smartphones", so it certainly sounds like the company's plans for QLC could lead to big changes for storage in general.
