True. IDE RAID done via software should be done with dedicated IDE buses - one drive per IDE bus (do not connect any slave devices), and preferably the a dedicated controller should be used for the drives you want to mirror. This way you still have your onboard IDE for your ATAPI CDROM. Promise makes a good IDE controller, i use it along with a 3ware, and you are sure you can get linux to do UDMA 66++ on each drive. It's important that you use UDMA, especially if you will use linux s/w RAID to implement it. If you use a controller that Linux does not know, worst case is that it won't be detected, and best case is that it will run in PIO mode which means you won't get the fastest data transfer rate from your hard disks. _ Philippine Linux Users Group.
