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...
