When SSD technology was introduced a few decades ago, it showed progress in terms of accessing data on a computer that could not be challenged by hard drives. Even so, one obvious drawback is the low storage capacity.
However, with the advancement of technology, SSD storage has become more powerful. Not only is it faster with a data transmission rate of several GB per second, but its storage capacity is also seen to have increased and can match what hard drives offer today.
Recently, it was reported that with the development of 3D NAND technology, which currently offers a capacity of 2TB to 4TB depending on the chip maker, will further increase to 8TB by 2029. This is thanks to the TLC (triple layer cell) and QLC (quad layer cell) technologies that allowing storage chips to be overlaid, increasing the amount of storage and allowing data to be accessed much faster than before.
In the meantime, the NAND chip technology itself, which is expected to produce a NAND chip with 4Tb storage is expected to be introduced in 2027, and an 8Tb NAND chip will be shown by 2029.
This means that we may see SSD storage with capacities up to 8TB within five years, and SSD storage with 2TB and 4TB capacities will soon become more common.
