Samsung’s new 4TB SSDs will be cheaper than ever before

Samsung’s new 4TB SSDs will be cheaper than ever before

This is all thanks to the more efficient production of 4-bit QLC NAND flash memory, while retaining the same performance level as a 3-bit SSD according to Samsung. 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).

Samsung has announced that it will begin mass production of the industry's first 4-bit (QLC, quad-level cell) 4-terabyte (TB) SATA solid-state drive (SSD) for consumers.

Samsung will introduce the headlining 4TGB QLC SSD, as well as 1TB and 2TB models in the 2.5-inch SATA 3 form factor later this year.

The company says that when data stored within a memory cell is bumped up from three bits to four, maintaining optimum performance and speed becomes "considerably more hard".


However, Samsung says its new SSDs are on par with the performance of its three-bit SSDs, achieved by using a three-bit SSD control, its TurboWrite technology, and boosting capacity by using 32 chips based on its 64-layer fourth-gen 1TB V-NAND chip. Once this has flooded the market, Samsung promises that 1TB SSDs will become much more affordable as a result. But Samsung says its upcoming 4-bit 4TB QLC SSD boasts the same performance as a 3-bit SSD.

Samsung's current 4TB SATA drive, the 860 Evo, costs upwards of $1,000. The company will also offer M.2 NVMe SSDs for enterprise this year. Pricing and release information wasn't mentioned in today's announcement, but we'll keep our ears to the ground for more.

Samsung boasts that its QLC SSDs will improve efficiency for consumer computing, including in smartphone storage where the 1TB four-bit V-NAND chip will allow it to efficiently churn out 128GB memory cards for smartphones.
