Samsung sounds death knell for hard drives with 4 TB QLC SSD

"As we expand our lineup across consumer segments and to the enterprise, 4-bit terabyte-SSD products will rapidly spread throughout the entire market". Stack enough of those together, and you can get a lot of storage in the standard 2.5-inch SSD form factor at lower costs.

Samsung has yet to reveal the all-import prices for the new devices.

This makes it considerably more hard to maintain a device's desired performance and speed.

As Samsung notes, this is a massive step up from the 32GB one-bit SSD it launched in 2006, followed by its two-bit 512GB SSDs in 2010, and three-bit or triple-level cell SSD in 2012.

Samsung has announced that it has begun mass producing the storage industry's first 4-bit 4-terabyte SSD drives.

With the amount of data being stored in each cell increasing from three bits to four, performance and speed of the new SSDs were expected to decrease.

Samsung is also planning on adding 4-bit fifth-generation V-NAND technology to its M.2 NVMe SSDs geared toward the enterprise.

And Samsung reckons this SSD tech will filter through the rest of the memory world, which could yield cheaper high-capacity SSDs for consumers.

The 4-bit QLC SSD promises a sequential read speed of 540MB/s, and a sequential write speed of 520MB/s.

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

Samsung says it plans to also release 1TB and 2TB versions and that the first ones will be available later this year.

The Samsung 4TB 850 EVO SSD is now listed on with a £1,399.99 retail price (albeit discounted to £999.99 at present). And Samsung predicts that its new 1-terabit 4-bit V-NAND chip will enable the company to produce large capacity memory for smartphones, too.
