I'd just make sure the drives were fast, that the MB supported ATA100
and that you used 80w IDE cables. My Soyo Dragon Plus gets fairly good
throughput; unfortunately, my drives are too slow, which means the total
performance would be better than:

In my experience it takes at the most 5 minutes to resync the
(on-average) 2GB partitions it is cut up into.
This board also includes Promise IDE Hardware RAID, but I've never used
it and can't comment on its performance.
Take care,
