The beginning of Section 4 of the Linux Sotfware-RAID-HOWTO
states emphatically that "you should only have one device per
IDE bus. Running disks as master/slave is horrible for
performance. IDE is really bad at accessing more that one drive
per bus".
Do the same cautions apply to building a RAID array using
SATA-II disks?

SATA is a point-to-point serial connection, totally different technology.
