need performance comparison between raw disks and HP raw logical vols

i would be interested in hearing of any real world evaluations of the decision to build a Sybase 10.0.2 database upon raw devices vs the HP raw logical volumes.

the disk architecture is based on two  fast+wide scsi controllers, each managing 8 2G drives, with the server supported by a UPS

the logical volumes were created to provide duplexing across controllers, and to allow a reads and writes to use the first available drive in the mirror.
