Samsung’s faster, cheaper 4TB SSD enters mass production

Samsung is also promising to use the 1Tb 4-bit V-NAND QLC chips to produce new 128GB memory cards for use in smartphones and tablets. 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. That charge is used to read information from a sensor, so it's much more hard to maintain performance over time. 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.

Based on the company's 64-layer vertical NAND (V-NAND) stacked design, Samsung's announcement comes with a world's first: the confirmation that the company will release the market's first quad-level cell (QLC) 4TB SSD for consumer use, based on SATA connectivity - and it's doing so using a three-bit controller, oddly.

As the chip capacity per unit area rises from 3 to 4-bit, electric charge can decrease by as much as 50 percent.

As a result, sequential read speed is given as 540 MB/s and sequential write as 520 MB/s, though random read/write figures have yet to be revealed.

Samsung plans to introduce 1TB, 2TB and 4TB SSDs later in 2018 in the laptop-friendly 2.5-inch form factor.

And if you're anxious about reliability, know that these drives will have a pretty generous three-year warranty.

Samsung didn't mention a price for any of the upcoming SSD models.

Pricing is yet to be revealed but the new drives are expected to be significantly cheaper than the Samsung EVO series now available.

"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 & marketing at Samsung Electronics. We now have no indication on pricing.
