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!
Features of the Promise FastTrak100 IDE RAID Controller
Visual concepts of RAID 0 (striping) and RAID 1 (mirroring)
Drive Support
EIDE, UltraDMA-33/66/100 drives
Drives Required
2 (maximum 4)*
Data performance (RAID 0)
Doubles sustained transfers of attached drives**
Data Storage (RAID 0, JBOD)
Links multiple drives as one large drive (C, D, or other)
Data Protection
(RAID 1, RAID 0+1)
Send identical data to two drives (or drive pairs) per save;
rebuilds data in background; supports “hot” spare drive (RAID 1
mode only) in case of failure
Onboard BIOS support
Automatically identifies type of drive; allows booting from any
drive array
RAID Levels
RAID 0 (striping 2-to-4 drives)
RAID 1 (mirroring 2 drives)
RAID 1 + spare (3 drives)
RAID 0+1 (4 drives only)
JBOD (spanning 2-to-4 drives)
