Actually 15 racks if you’re using backblaze storage pods. Which now that I think about it, is about how many racks I saw in the various rooms of the church. [I just happened to be at IA headquarters last weekend.] The storage pods hardware itself would be another $1m, and then let’s assume other $0.5M for various things I’m not considering (network equipment, power transformers, etc.). Still just $5m for the base hardware to store that info.

Yeah, pretty affordable.
