It does look like one big drive, instead of 2 smaller drives. I don't think
the total space gets much smaller than the total formatted space of the
2 separate drives. The only things RAID-0 give you is more speed and
a larger unified disk space. If you loose any of the drives in your
RAID-0 array, all of your data is gone. There is no redundancy. I'm using
a RAID-5 array. It has 4 drives, but you only get to use the space of 3.
A space equal to the one of the drives is used for redundancy (don't
ask me how). If any of the drives fail, the array will not loose anything
and will continue to be usable while it tries to rebuild itself. If the
failure
of the drive is fatal, then you have to swap out the defective drive and
then it will attempt to rebuild itself again (in the background). It doesn't
improve the speed though, in fact it slows down the drive access a little.
