96 layer 3d nand ssd drives are on the way
Table of contents:
Although researchers expect 3D NAND flash technology to reach 140 layers by 2021, the technology and manufacturers have yet to take all the intermediate steps before that happens. In this sense, Western Digital has just announced that it is on the way to produce the first 96-layer 3D NAND units and distribute it to its customers.
Western Digital Promises First 96-Layer 3D NAND Units Coming Soon
For now, the memory will be used for low-cost storage solutions, but the idea is to increase production for other higher-performance products.
Western Digital CEO Steve Milligan has kept production acceleration a secret (and the expectation that BiCS4 production will outpace BiCS3), but it seems that everything is going smoothly for the first units. with 96 layers.
More layers for SSD drives means more storage capacity, and therefore lower cost per GB, which is currently one of Achilles' big heels for solid drives.
As Western Digital announced earlier, this initial production is likely delivering 256GB capacity chips, with performance enhancements to allow for future capacity growth, eventually up to 1TB of capacity per chip.
At this time it is difficult to anticipate when the first 96-layer units will be in stores, but possibly it is for 2019.
