Although the price of flash memory has risen recently, SSD hard disk has also gone up rapidly, but basically everyone will choose SSD instead of HDD mechanical hard disk for installation. After all, the performance gap is too big.

Since then, IBM's HDD technology has reached its peak in 1973, with more than 200 HDD companies.

In contrast, SSD drives are much younger,The world's first SSD is believed to be launched by Sandi in 1991,It had a capacity of 20MB. At that time, it was selling for $1000, which was a sky high price. Only IBM's ThinkPad notebook could afford it.

In contrast, SSD production is much simpler. Basically, PCB, flash memory, master controller and a shell are enough. Flash memory is mainly purchased from the six largest flash memory manufacturers in the world, and so is master chip.

Thanks to this, more and more manufacturers are entering SSD industry,The latest data shows that there are more than 200 SSD manufacturers, and the distribution is also very interesting. The United States accounts for 40%, which is the largest number of manufacturers.

Chinese mainland and China Taiwan manufacturers accounted for 13% and 22% respectively, while Japan and Korea were 6% and 4% respectively, and the share of other countries was much less.
