The difference between traditional mechanical hard disk and solid state hard disk

Solid-state hard disk has great advantages in transmission speed, up to 500M/s, in which the reading speed is 400-600M/s and the writing speed is 200M/s. For the file of 1G, it only takes a few seconds, but the reading speed limit of traditional IDE hard disk cannot exceed 200 m/s and the writing speed cannot exceed1000 m.

2. The difference between price and capacity:

The space of SSD with the same capacity and price is not as large as that of traditional mechanical hard disk. If you pursue capacity and don't care much about speed, naturally choose mechanical hard disk.

3. The third hard disk is a hybrid hard disk:

Hybrid hard disk combines the advantages of both, but its speed is still not as fast as pure SSD, but it is faster than traditional machinery, and its capacity also absorbs the large-capacity characteristics of traditional hard disk.
