This may be possible, among other things, thanks to eight-bit memory.
Such progress will be facilitated by the continued process of scaling current solutions, both in terms of reducing the physical size, and in terms of improving technical processes. As a result, the size of NAND flash memory cells will continue to decrease, the number of layers will increase, and each layer will be able to store more data on its own.
1PB SSDs could be available within the next 10 years. Such forecasts are given by Samsung
Now Samsung says that in the future it is possible to release memory that can store 8 bits per cell.
True, if you look at the progress over the past 10 years, then the first 1 TB consumer SSD was introduced in 2011. Now ordinary client drives have a maximum capacity of 8 TB, and if we talk about specialized solutions, then the same Samsung offers a maximum of 30.72 TB for one SSD, although this model was released back in 2017.
