Earlier this year one of my 2TB drives failed and I lost the whole drive. It wasn't anything that I was worried about but it got me really worried about my real personal info. So I have decided to do buy an external RAID enclosure. I have looked at NewEgg, OWC and Apple. I found a decent little enclosure from NewerTech, the Guardian Maximus. I thought this was a great idea until I read this: "Thing worked great for quite awhile, but then the enclosure's electronics failed. The biggest problem with that is you can't insert your old data (on the existing drives) and reuse them. I was told by Newer Technology the enclosure always reformats a drive when it is inserted. There goes that sound backup strategy." So is there a RAID enclosure that won't do this? It's bad enough that I have to worry about the HDDs failing, now I have to worry that the unit could fail and force me to erase the drive if the enclosure breaks.
