Appendix I: RAID Installation (optional)
Introduction to the Promise FastTrak100 IDE RAID Controller
The FastTrak100 can stripe multiple UltraDMA/100 hard drives together under RAID 0; mirror the data on
two drives under RAID 1 (master only); or do both for maximum speed and protection under RAID 0+1.
Under mirroring, should one drive fail, the remaining drive will handle all data. When a new replacement
drive is later installed, the FastTrak100 rebuilds data to the new drive from the mirrored drive to restore
fault tolerance. Up to 4 drives* can be linked to the Promise FastTrak100 RAID controller, effectively dou-
bling their sustained data transfer rate**. The FastBuild™ auto-menu allows for quick and easy array
builds. NOTE: You cannot install any devices other than HDDs on the RAID IDE channels!
