What about a float array, float[]?
you seriously don't want to use bytea to store anything, especially if the datatype matching exists in db of choice.
also, consider partitioning it :)
Try to follow rules of normalization, as with that sort of data - less storage space used, the better :)
And well, I would look for a machine with rather fast raid storage :) (and spacious too).
