95% Columns are varchar2(5 byte)
it is staging table so no indexes are there
no compression o tables
pctfree is 10

Are those 150 blobs, each of which contains blu-ray content? or are they 150 char(1) fields?
Also need to take into account indexes which may fill the same or a different tablespace as the table.
Also need to consider if you have compression on the table, indexes, or tablespace and what kind of compression.
Then need to know the actual data to determine just how compressible it is.
Also need to know the pctfree defined for each.
