Size of database

Hi,

I'm trying to take care of the size of my databases on disk.

I have a table with mio of records.
One field contains a name, which is a StringField of 40 chars size.
Unfortunally almost 80% of all data have a name much shorter then 40, so here 
is a lot of space "wasted".
Is it maybe better to use a TextField in this case? What about the compression 
flag?

Another field is of type Blob.
How does the segment-size affects the unused space?
It seems, that the minimum segment-size is 128?

Best regards,
Tom
