How to make factory machine hard disk drive more durable? How much its estimate life span?
Quite likely, the SSD killer is electrical. We can't entirely rule out mechanical vibration, but SSDs are pretty robust mechanically. A simple rubber mounting would increase the resiliency even ...

How is "16.7 million colors" in a display calculated?
Each color red, green, blue that makes a pixel has a range of 0 to 255. So each of the colors has 256 possible settings. 256*256*256=16.77 million possible colors.
