I found that if I ccd'd the two Maxtors I have their combined throughput dropped to about 15MB/sec. That is with each drive being the only thing on an IDE controller on my motherboard (my cdrom is SCSI). I wasn't expecting to see much improvement over 27MB/s, but I was not expecting a drop. Pilot error? Expected behaviour? I don't know. I'm happy without ccd, to be frank. It served it's purpose well when I was using old, slow SCSI disks. I hope you have better luck with 3Ware, but I'd check to make sure. Kees Jan ================================================= TV is the worst of both worlds.
