I am looking at getting a raid card with the plan of running 6 Western Digital 640GB drives. I operate Windows XP, Vista, and Linux 64bit. I have narrowed it to the Areca 1220 and the Adaptec 5805. I like the cable management more on the adaptec, but I am not sure what the preferences are between these two cards. I haven't had much information on the Areca, but the Adaptec has been a little more elusive. Thanks for any help.
