we're using a backup server equipped with a 3ware controller. the
motherboard is a simple desktop board, so we're using a normal pci
interface. we've never had a problem, and even though using standard
pci, the speeds are fairly good (surely not top of the bill though). the
configuration is 3-disk raid5. fyi, here's the hdparm test:

 Timing buffer-cache reads:   128 MB in  0.21 seconds =609.52 MB/sec
 Timing buffered disk reads:  64 MB in  1.43 seconds = 44.76 MB/sec

i've tested disk failures by just pulling out a disk and rebuilds went
fine. sure, 3ware's expensive and probably not the fastest out there,
but i'm very happy with it's stablity and ease of installation and
