quite some time. This saves time with the startup for the next read
operation but also causes noise and consumes extra energy. It makes
sense to calm down the drive if no read operation is expected for the
next few seconds. The drive will get alert automatically if operations
are required.

This is not mandatory to allow further drive operations
