On this note about "Adaptec junk", I have a question regarding hardware
as well. We tend to build a lot of servers in house (Supermicro based
with the Zero-channel raid). Does anyone have any anecdotal or empirical
data on using a ZCR card versus a full-blown RAID controller (adaptec or
other)?? I am trying to build a medium-duty database server with 8G RAM,
4x144GB U320 Scsi RAID 10, FreeBSD (5.3-stable or 4-stable) and was
wondering about performance differences between ZCR and Adaptec versus
other manufacturers' Full-RAID cards. (PCI-E)
