Which is better, Samsung or Hitachi, a 2.5-inch notebook hard disk?

Hitachi is the most professional notebook hard disk, because Hitachi's original vertical recording technology is very advanced, especially suitable for small hard disks. Samsung's hard disk can only be said to be average, but the price is more expensive than Hitachi's. Now ASUS, Dell and IBM all use Hitachi's hard disk, which is of course reassuring. Hitachi is not good, and picky IBM disdains it.

Five patents of Hitachi hard disk:

First, liquid bearing motor technology, ultra-quiet working environment

B, magnetic head loading and unloading technology, more effective and safe data protection.

C, magnetic head flight compensation technology, faster data reading speed, shorter system startup time.

D, built-in thermal sensor technology, effectively control the calorific value of the system, and the data is more secure.

E, vertical data recording technology, innovative data recording methods, and challenge the capacity limit.
