Recently, Intel, Micron, Western Digital, Toshiba have announced their progress in 96-layer stacked flash memory, QLC flash memory, and Samsung Electronics, the world's largest flash memory manufacturer, is not to be outdone, and has already announced mass production of 96-layer stacking. Five generations of V-NAND flash memory, and announced that it will launch the world's first 32TB ultra-large capacity SSD during the year.
Samsung just produced a 64-layer stacked fourth-generation V-NAND last year, and the latest fifth-generation stacking layer has increased by half, reducing the physical X, Y size, performance and power on the wafer, and using Toggle for the first time. DDR 4.0 interface, data transfer rate of up to 1.4Gbps, 40% higher than the previous generation.
According to Samsung’s vision, 3D stacked flash memory can exceed 200 layers in the future.
Samsung also revealed that It has already launched 3D TLC flash memory with a capacity of 1Tb (128GB), data transmission rate of 1.2Gbps, and supports 32 stacked packages, thus achieving a single capacity of 4TB.
Samsung's future PM1643 series SSD will use this kind of granules, the maximum capacity can be 32TB (only eight chips), and the storage capacity of the previous two cabinets can be realized in only 4U space.
This new hard drive will be adopted 2.5 inch specification, SAS interface , known as Random read performance is 2.5 times higher than previous generation products , for the data center enterprise market.
Toshiba/Western Digital announced that the 96-layer stacked QLC flash memory can achieve a capacity of 2.66TB for a single packaged chip, and eight can also achieve an SSD of more than 20TB.
In addition, Samsung will also introduce QLC SSD, SATA interface for consumer-grade market, continuous read and write performance of 540MB / s, 520MB / s , but the specific model, specifications, time has not been announced.
In theory, QLC SSD can easily achieve 5TB or even 10TB of large capacity, but the starter will certainly not be so big, after all, we must consider the affordability of consumers, but according to this trend, 256GB, 512GB SSD will be able to go all the way next year. .
