which raid controller delivers the best performance with raid1 arrays?
Areca/Tekram ARC-1210, PCIe x8
AMCC 3ware Escalade 9650SE-4LPML, PCIe x4
Promise SuperTrak EX8350, PCIe x4
i know that 3ware speaks of a (up to) ~3,5 time performance increase due to "twinstore" (when using massive amounts of small parallel requests)
