Micron has simply introduced its subsequent technology of 3D NAND. At 176-layer, the brand new chip presents a 37% enchancment on its nearest competitor, Kioxia/Western Digital’s 112-layer BiCS5.
The corporate says the brand new NAND will enhance each learn and write latency by greater than a 3rd in comparison with final technology’s 96-layer floating-gate NAND, which may imply quicker and cheaper solid state drives.
The producer additionally claims to supply a die that’s about 30% smaller than aggressive choices and hits a whopping 1.6 gigatransfers per second (1600 MT/s) on the Open NAND Flash interface bus – a double digit enchancment on previous generations.
And right here’s the kicker: the 3D NAND chips are already in quantity manufacturing and transport to clients, together with in Micron’s personal Essential SSD product strains.
In the end, what the announcement means for the tip person is extra energy environment friendly, quicker, smaller and cheaper SSD designs. For the datacenter viewers, in the meantime, the brand new chips will ship endurance enhancements, that are significantly helpful in write-intensive use instances.
The 100TB ExaDrive DC SSD, the most important stable state drive at present in the marketplace, is probably going to make use of 64-layer SLC NAND, which explains its eye-watering value of $40,000. For comparability, the cheaper ExaDrive NL 64TB from the identical firm is probably going to make use of 96-layer TLC NAND chips, which slashes its value to a mere $10,900 – lower than half the fee per TB.
Micron’s new expertise may both imply extra SSD on your cash (e.g. 100TB for $10,000) or far cheaper price factors. In the end, the agency needs to drive aggressive, industry-leading price reductions that can hopefully trickle all the way down to the tip person.
Which means exhausting disk drive distributors like Seagate, Toshiba or Western Digital could need to watch their again within the datacenter/nearline market. Micron’s new chips may usher in a brand new technology of extraordinarily excessive capability 3.5-inch SSD drives at comparatively low entry factors to exchange current spinning drives.
