So, their "RAID" ability supported only by M$ Window$. Under FreeBSD they work as normal IDE/SCSI/SATA controllers. I've tested yesterday one of them - Adaptec on AIC 7899 chip. Take a look at hardware notes on 4.10, for example "Promise Fasttrak-33, -66, -100, -100 TX2/TX4, -133 TX2/TX2000" - noone except Promise calls it RAID...
