One thing to consider, depending on the size of the data, and the
kinds of searches you need to do...

My guess (based on a poor sampling size) is that moving data you're
not searching through out of the database (ie, stuff that you might
store in a blob or image field instead goes to a file) can be a good
strategy where its possible.

My experience has been that BLOB's are relatively slow to retreive
(though convenient to use)...  Anyone else concur or disagree?
