guy, the 500 GB vs. 465 .... this is a marketing trick of harddrive manufacturers ... they call 100o byte 1 kB, whereas 1 kB is in fact 1024 byte. this multiplies up to the difference you are now wondering about .... it's *normal*.
you said you choose raid 0 (striping), so in the end (after initializing of the device is finished) you should see only 1 drive with 1 TB (resp. the *true* 931 GB).
now format this drive with HFS+ extended (without the journaled option, for reasons i wrote above)
the raid tab is not applying to your case, because the raiding is done in hardware by your external device.
then i would run some tests for audio-streaming, i mentioned earlier that it is not sure the raidcontroller gives optimal performance for severeal reasons. if it does not, you should re-configure the device to JBOD (just a bunch of disks) - then you will see two drives in the disk utility and should raid them in software (that's what the raid-tab for) or leave it as it is and just spread your samples across the two new drives
