I am not explaining myself as I should have. First, to set the record straight, Raid 0 is not even really true raid ( Redundant Array of Inexpensive Disks). Now, as for a jbod setup, perhaps you are right, its a bit of tricky terminolgy. Lets say I take a controller, the qlogic 2100. I then connect three drives in a jbod config. Now, when using the right OS, (In this case win 2k or win xp) I can setup my array with these disks by that means. Now, if this then means the array is no longer a jbod, which after I think about it it very well might, then you are correct.
Another option would be to do the same except this time with two controllers and two seperate jbod configs, one on each controller, then stripe the two jbods.
This may sound rather costly but you would be amazed at what it can be done for.
9.1 gig 10k drives with 4 meg cache buffer( 6ms access) $10.00
18.2 gig 10k drives with 4 meg cache buffer( 6ms access) $26.00
36.7 gig 10k drives with 4 meg cache buffer( 5ms access) $50.00
qlogic 2100 64 bit ( 32 bit backwards compatable) $50.00
2-4 drive backplane $100-200.
Now campared to the cost of a IDE RAID 0 config, lets say 2 30-40 gig IDE drives and a promise raid controller, your going to find cost will be almost equall.
It's not what they tell you, its what they don't tell you!
