I was wondering about hardware raid. I know from research that Raid on Chip (RoC) usually refers to a hardware raid solutions for pci-e cards. I have looked at adaptec, lsi and areca. LSI and Areca in some cases use power pc and arm processors. For example, a card I am looking closely at is the LSI 9341-4i 12gb card to potentially purchase. I know it doesn't have cache ram but uses a power pc processor and is not called a Raid on Chip solution. The question that is burning me is this: aren't ARM and power pc processors also hardware solution since they use hardware processors for the raid processing? Or are power pc and arm processors a hybrid hardware solution?
