hi,
what is the performance difference between two 3ware 7500-8 PCI card on
a 32 or a 64 bit PCI slot if used with 8 pieces of 120GB hard disk (and
linux software raid5:-). I know there is not an exact measurment, but
what is your estimate?
thanks in advance.
yours.

You will be limited by the PCI bandwidth on the 32bit bus (133 MB/s -
whatever else you have on the bus). I've benched a single board at
~200MB/s reading using the hardware RAID 5.
