Melco Audiophile NAS

What a lot of music :-)

For security, having copies on multiple devices is better than raid on a single device.

You could try loading a few of your favourite test tracks on as spanned, have a listen, then reformat as raid 1, reload the test tracks and see what you think. If you hear no difference then you could swap out for larger disks and run raid 1 so you'd have 3 copies.

I have a copy of my music on the Melco, one on my desktop PC, on a raid QNAP and finally on a third party online backup server. Just a bit paranoid.
