But this is for my usage, this is a bare enclosure so you need to put in a SATA hard drive also. Redundancy is something else you might want to think about.
If you have no clue in these things, then its best to speak to someone who knows about them and discuss what you want to achieve.
Me? I will be no good, as I have just had my qnap delivered and not even loaded it with a fat drive yet!
