I guess that would be the obvious choice... Just a lot of storage
space reqired I imagine.

Any more normalized and I'd have 216 billion rows! Add an index and
I'd have - well, a far bigger table than 432 million rows each
containing a float array - I think?

Really I'm worried about reducing storage space and network overhead
- therefore a nicely compressed chunk of binary would be perfect for
the 500 values - wouldn't it?
