And that my friend is why I have a whole wack of UPS's to protect and power all my computer devices.
As for your RAID. have you considered setting up as RAID6, or even if your RAID5 can have a hot standby?
Did you put on the 044 firmware onto your Anthem? I don't know what is different between the 039 that I had, but hope it fixes something more that i didn't know i had.
