This is a big improvement. When using ZFS with mfi(4), mfiutil(8) can be 
used to create an "un-RAID" configuration by creating several stripes 
spanning single disks. The MegaRAID BIOS does not make the relevant 
options easily available. Having native CAM support for each disk will 
be a big help here.
