USB drive for temporary file area

I notice that when running a defrag, the program uses the end of the hard drive as a temporary holding area for files. I suggest, if possible, giving the option to use a USB drive (or secondary hard drive) as a choice for this. That way the program can be reading and writing at the same time instead of reading and then writing, thus making the program faster. At least that's how it works in my mind. Added bonus would be for it to check those drives and verify they have enough space available to do this.

Thanks for your time,

Using an external hard drive makes sense (but it could be potentialy risky for losing data). Using USB or SSD is a no-go as you would shorten drive lifespam.

This would bring a big speedup. On my drive I have speeds at 20 MB/s copying from disk to same disk,

but speeds up to 50 MB/s copying from another drive to my Harddrive.

And as you do not fragment every two days a seriously fragmented partition,

the Flash Memory wouldn't be overused. It should endure >1.000.000 Writes as I remember
