A solution to slow Macrium mirror creations

I changed the SATA connections randomly.

Full mirror backup with verification of the 31Gb system drive took five minutes and 5 seconds. The compressed file is 20Gb. Previously, it took 18+ minutes for the same operation.

Some helpful details.

* Write down the devices' boot order in the BIOS/UEFI
* I am using the free Macrium version.
* Always full backups.
* Source disk is a 120Gb SSD.
* Target partition is a Seagate Barracuda 7200rpm.

This was a chance discovery. There are five connected SATA devices to the MB and had to disconnect them to get to the sixth. Then, reconnected them randomly.
