>Do you have real problems with disk space? Generally speaking, if your database is structured properly then half-empty character fields should be the least concern. Maybe you can split this field on two or more and/or use related table, but I would not recommend using memo just because you want to save space. Memo is used when you want to keep more than 255 characters.

And with memo comes bloat and memo file corruption.
