That's the same math we came up with, Russell.
In fact, here's from another recent post in the FCP forum that I wrote:

"No doubt catdv is the bees knees.
Cache-A has an extremely simple
database that allows searching.
As far as redundancy, we keep a set
local and a set offsite.
As far as speed, it runs at about 68-70 megabytes/sec so FireWire 800 speed. When tranferring 800 gigs from a single drive of any type will take a bit of time.
We thought long and hard about what to get. We had over 35 sata drives sitting on the shelf, it was time to either purchase another set of drives to add redundancy, or look for
something else. At the time, LTO was really the only cost effective way to do it. Buying
40TBs worth of raid protection, or 40TBs of more SATA drives, plus a server to run catalog software that could be run throughout our 'facility' wasn't making much sense for a number of reasons. The LTO tapes are cheap, easily transportable and the CAche-A has it's own web server with a rudimentary catalog that can be acessed from any computer on the network. It made the most sense at the time, and it is still making sense for the forseeable future. In the process of archving the 40TBs to LTO, one of our newer 1TBs drives failed to spin up. It's gone and lost forever even after sending it to Drivesavers. Now, even if something happens to our office, the offsite tapes are safe. It's worth at least throwing it in to your pile of considerations for long term archive. "
