I've noticed that some of these U320 SCSI cards, e.g. Adaptec ASC-39320A, are dual channel, that is, they have two 68-pin connectors for U320. The manual mentions that this is done so that you can have one channel for U320, and to use the other channel for more legacy devices. This way, your U320 channel isn't slowed down by being on the same channel as legacy devices.
This card also supports RAID 0, 1, and 10. I was thinking of setting up RAID 0 (stripe), which is supposed to increase performance compared to mirror. The manual doesn't specifically say anything about setting up RAID with one HDD on channel A and the other on Channel B. My question is: Is there any performance or reliability benefit of having both HDD's on one channel, or to split the HDD's up between the two channels?
