In 2016, Samsung launched a 4TB SSD with a prohibitively expensive $1499 price tag. In a statement this week, Samsung revealed that it has started mass producing a less expensive variant, ushering in the industry's first 4-bit quad-level cell (QLC) 4TB SATA SSDs. The 4TB model will be part of a consumer QLC SSD lineup released later this year alongside 1TB and 2TB capacities.

The three new consumer-tier QLC SSDs will utilize a 2.5" form factor, making them compatible with a variety of PCs and external enclosures. According to Samsung, these SSDs have a sequential read speed of 540MB/s and write speed of 520MB/s, offering the same performance as 3-bit drives via the use of TurboWrite tech and a 3-bit SSD controller.

In a press release, Samsung executive VP of memory sales and marketing Jaesoo Han said, "Samsung’s new 4-bit SATA SSD will herald a massive move to terabyte-SSDs for consumers." In addition, the company says its new 1-terabit V-NAND chip enables it to efficiently produce 128GB cards for mobile devices, paving the way for high-performance mobile storage.

Prices and release dates haven't been revealed yet.
