Most (serious) safes are capable of withstanding a fire or a flood.
I don't have near the volume of pictures that you have (around 1.5 TB) but here's my setup:
- one disk attached to the Lightroom computer, with all images on it; it's local, so it's fast
- one NAS (NAS1) with a 4-disk RAID that backs up this drive (3 TB capacity)
- another NAS (NAS2) with just one 3 TB disk that backs up the other NAS
On NAS2 I rotate disks; disk A is in the safe when disk B is in the NAS.
I think my setup is quite similar to yours, except driving is replaced by "going to the safe in the basement".
If a disaster happen I should have at least the disk in the safe intact, which holds the data since the last rotation; and since backups from NAS1 to NAS2 are quite fast I try to have both disks pretty much in sync (after an important shoot I back up to disk A AND disk B).
Of course I won't know if this setup is good until my house does burn down (I hope I'll never know!) but it does give me peace of mind, which is at least something ;-)
