"As we expand our lineup across consumer segments and to the enterprise, 4-bit terabyte-SSD products will rapidly spread throughout the entire market".
You can look forward to the initial 4TB QLC SSDs arriving later this year. But Samsung reckons that by using a 3-bit SSD controller, TurboWrite technology and making use of 32 fourth gen 64-layer V-NAND chips, the new 4 TB QLC SATA SSD doesn't suffer such a performance drop. A new round of NAND flash production at Samsung could finally make SSDs in the multi-terabyte range affordable and mainstream.
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.More news: Ben Stokes trial: Jury shown CCTV footage of ‘groin grab’
Samsung's announcement this week sees the company start mass producing quad-level-cell (QLC) which allows for a 1Tb capacity per chip.
The company said that as data stored within a memory cell increases from three bits to four, the chip capacity per unit area would typically rise and the electrical charge - which is used to determine information from a sensor - would decrease by as much as 50%. While we probably can't expect this 4TB SSD to be cheap, Samsung does say that it will also be introducing 1TB and 2TB 4-bit QLC SSDs later this year.
As to performance, Intel claims its 660p SSDs deliver sequential reads and writes at up to 1,800MB/s (sequential), with 4K random reads and writes checking in at 220,000 IOPS.More news: Hiroshima marks 73rd anniversary of atomic bombing - 8/6/2018 12:45:44 AM
Samsung has announced it has put production of its first consumer QLC SSD into overdrive.
The Samsung 4TB 850 EVO SSD is now listed on Amazon.co.uk with a £1,399.99 retail price (albeit discounted to £999.99 at present). The company added that it is also working on a 128GB QLC memory card for smartphones.More news: Carrie Underwood and husband Mike Fisher expecting baby No. 2
