Hi,

|For a Database of 20 GB, regarding the speed, is it better to use RAID 0 or
not ? I read that read 0 is twice more faster BUT is
|it true when we speak about only one file (the .GDB) ?

I wouldn't use RAID 0 !! It would not be safe for your Database.

RAID 1 is simple (cheap), safe and will also improve speed for your reads.
I've been using it with great results.

Also, If you can afford and need something even more "secure" than you may
want to try RAID 10.
