Does plugging in a flash drive all the time harm it?

[Pankh]

I have a Sandisk flash drive, the tiny one with 128Gb storage and I'm working on an early MacBook Air. Is it going to cause any damage if I just leave the drive in the port all the time. Because I can feel that it's generating some heat even if there is no operation regarding it.

There is no harm if you keep flash drive plugged in USB.

It can be warm - it can transfer some heat from the computer through the metal connector and it can also generate a little heat as there is probably a DC/DC converter from 5V down to at least 3V3.
