This is a follow up for my previous question: [Blob and Storage Requirement](https://stackoverflow.com/q/8931696/1159190)

I did some testing using `SHOW TABLE STATUS`, and found out that the total disk space used actually only depends on the size of actual files uploaded to the database and not on the type (e.g. TINYBLOB or LONGBLOG) of the column.

So, if that's not the case then what difference does make when we choose one over the other of the BLOB types?
