I would be very interested to hear if anybody has tried out SATA
hardware RAID with high-performance (WD Raptor or similar) SATA disks on
their Cyrus server? In particular, experiences with the WD Raptor 73GB
disks, as they might be a reasonable alternative to a SCSI array. I'm
sure other Cyrus users would find the information interesting, too.

I'm using SATA RAID here, but with normal WD and Seagate disks - desktop
IDE drives with a different plug, really. My user count is tiny, but
disproportionately hard on the server, as most of our clients seem to
think that email is made for lobbing 100MB TIFF files around. *sigh*.
The server also has a lot of other roles, and really feels the disk
load. As a result, if anybody has experience with the high-end SATA
disks, I'd be very interested in hearing about it.

I suspect the big difference would be TCQ support...
