Totally agree that individual drives (and even small redundant boxes) aren't usually a good choice for long term storage yet tape drives have their own cans of worms. Besides cost of entry and limited fault tolerance, one of them is portability. You have to have the tape drive and install the software to read the data. Might cause issues for an IT-challenged facility.
With that in mind, G Speed Q (along with Drobos, CineRAIDs, etc.) might be that balanced choice for long term storage, for a small IT-challenged facility: fault tolerant to a degree, portable, immediately available. For long term storage viability, I'd add a couple of things along the lines of Vince' advice to "spin 'em once in a while":
- keep it online and connected to one of the systems for constant health monitoring;
- consider getting a spare drive module;
- see which one of all of these boxes offers the best diagnostics and reporting so that you absolutely and immediately are notified if there is anything wrong with the box or one of the drives;
- limit permissions so that the data can't be easily wiped out or messed with accidentally.
I'd venture Drobo has the best monitoring tools, but would need to do a little more research on it.
Frank: you can also offer a small service (which you can charge for): check on the health of the unit every month or three: check RAID and individual drive statuses, system logs for related error messages, integrity of the file system.
(What do you think about it Vince?)
