Samsung has announced the serial production of 4TB consumer SSDs, designed to improve storage for notebooks and other devices.
Samsung has released no official prices for in- production drives, but the 4TB 860 Evo currently sells over for $1,000. For comparison, you will receive a 4TB mechanical drive for $100.
The new SSDs are the first to use 4-bit quad- level cell technology( QLC) and the 4TB version uses 32 128GB chips in total. Performance is on par with older 850 Evo drives with read speed of 540MB/s and write speed of 520MB/s.
Samsung says its new technology prevents the memory cell problem from going from three to four bits, which would generally reduce efficiency by 50%.
Later in 2018, Samsung plans to introduce 1TB, 2TB and 4TB SSDs in a 2.5-inch laptop- friendly form factor. This year, the company will also offer M.2 NVMe SSDs for the enterprise.
Samsung says it also hopes to use technology to make 128 GB smartphone memory cards.
With the expected launch of Samsung’s 512 GB Galaxy Note 9, which will join a growing group of half terabyte mobile phones, the need for additional memory cards may decrease.
The other way to look at things is that these phones now exist because we want more and more space on our phones.
