Samsung Begins Mass Production of 4-Bit 4TB SSD for Consumers

Posted August 7, 2018 at 3:00pm by iClarified
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’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. “As we expand our lineup across consumer segments and to the enterprise, 4-bit terabyte-SSD products will rapidly spread throughout the entire market.”

The company says its 4-bit 4TB QLC SATA SSD maintains its performance levels at the same level as a 3-bit SSD, by using a 3-bit SSD controller and TurboWrite technology, while increasing drive capacity through the use of 32 chips, all based on 64-layer fourth-generation 1Tb V-NAND. This will enable a sequential read speed of 540 MB/s and a sequential write speed of 520 MB/s.

Samsung plans to introduce several 4-bit consumer SSDs later this year with 1TB, 2TB, and 4TB capacities in the widely used 2.5-inch form factor. The drives will come with a three year warranty and should be significantly cheaper than the current 4TB SSDs that cost about $1051 for the Evo and $1695 for the Pro.

Apple will be slow because it will impact revenue on the cloud storage. It’s about revenue not about giving the customer what he wants

It’s sad to say my iPhone has more storage space than the new MacBook Pro.

Apple will be the absolute slowest to adopt any of this of course.
