Is it true that the bigger SSD system space reservation is better?

2019-11-01

Reserve space = (actual capacity - user capacity) / user capacity

Analysis of how much capacity of an SSD is the best deal

2019-10-29

The rationality of hard disk partitioning cannot be generalized. After all, our needs are different. We need to set reasonable and optimal partitions according to individual’s need. For example, if there are more game programs, we can partition more for the game disk; if there are less software or little common software, we can partition less for the software disk.

5 most expensive chips in the world, which is worth the value of a house

2019-09-03

Chips are the most important components in semiconductor industry. Despite its traditional qualities like high-speed computing, storage, logic capabilities, collaborative processing, and many other high performances, a chip need to be flat enough, reinforced, heat dissipated, and can resist high temperature before it can be applied in aerospace or in military use. Since it’s a world class mystery to make such a chip, the US and European countries have invested heavily in this field, and have strict control over its shipment. Since China is their main rival, it is hard to buy one to China.
