Hello,
We are considering using BLOBs in our Oracle 9i database( supposed to be migrated to 10g soon)
Here is the scenario
· 20 000 BLOB/year keeping during 5 years
· 100 inserts per day
· 200 reads per day
· Maximum BLOB size is 150 Kb
What will be performance impact of using Blobs on INSERT/SELECT ?
Would it be better to separate BLOBs on the different tablespace ?
Thanks in advance
Alexander

I suggest you write a small benchmarking routine and test it yourself. It would be great if you can post your results here as well.

Why not - do it anyway.
