All other things being equal, software RAID is going to be faster. (ie.
same disks, same # of SCSI channels, etc.) The hardware solution's sell
there is:
- better support/functionality (enclosure management, etc.)
- better survivability (battery-backed cache)
Plus you get a stack of SCSI channels onboard the card.
