BTW, I'm not dissing on your product at all (and apologize for going off on a tangent). It could be that Arq is the glue that makes Glacier far more superior than any kind of personal storage solution. I'm just bickering about the cost of Glacier alone...but otherwise, I think it's great to have a Glacier-accessible option.
I didn't take it as a criticism of Arq. I wish costs were lower as well. On the other hand, I see there's a big difference between a hard drive vs bottomless storage that's remote, replicated, durable, and "always" accessible, so the cost doesn't seem so high to me. I've been of the opinion for a while now that the safest way to store bits is on spinning hard drives -- safer than DVD, tape, turned-off hard drives.
