Why can raid0 mode reach 45m/s,

Why can raid0 mode reach 45m/s, and the same hard disk raid0 mode can reach 95m/s on other machines?

How did you test that?

Copy files, the same hard disk will be faster in the mobile hard disk box

Is it the same to use the Raspberry Pi test with a mobile hard disk box?

Not the same, the difference is far. The raid performance of the Raspberry Pi is quite poor
