We'd like to use the 3ware 7000-2 in non-RAID JBOD, to get the supposed speed benefit of the 3ware "switch fabric", lower CPU overhead, etc. in high-volume SMTP relays. Will whatever 3ware+FreeBSD somewhat "discutable" 3ware problems show up in JBOD mode or are the problems limited to RAID? Does anybody have experience or URL that says the 3ware 7000-2 @ $100 is sufficiently "better" to justify it over an Promise "Ultra133 TX2" @ $40? Len
