Mediocre performance, random lockups, and Dell's refusal to address
said lockups are the reasons I abandoned Dell's PERC controllers. My
preference is Areca 1680/1880, then 3Ware 96xx, then LSI, then
Adaptec. Areca's web interface on a dedicated ethernet port make them
super easy to configure while the machine is running with no need for
specialized software for a given OS, and they're performance and
reliability are great. The 3Wares are very solid with later model
BIOS on board. LSI gets a rasberry for MegaCLI, the 2nd klunkiest
interface ever, the worst being their horrible horrible BIOS boot
setup screen.
