MacPro 3 drive RAID Possible?

[jazz1]

Is a 3 drive RAID0 possible in Apple Disk Utility for a MacPro 2.66? I was told that this was not possible when I went shopping for three drives. I was pretty sure I'd seen three and four drive RAIDs discussed here, but maybe they were different kinds of RAIDs, not a RAID zero. Maybe my question was misunderstood by my salesperson?

I haven't tried it, but I'm pretty sure you can.

Normally when we talk about RAID using more then two drives we are talking about RAID-5. Mac OS can't do software raid5.

You want to concatenate three drives in a raid-0 setup? That's not really a good idea. You'd be three times as likely to loose data then if you did not use RAID.

I have a 3 drive WD raptor raid 0 that absolutely screams. The 4th drive serves as a bootable clone and TM storage.

Very robust and reliable.

As noted above, you could do a three-drive RAID 0 setup in software, but be sure to have Time Machine backing those babies up every hour.

To do a three-drive RAID 5 setup requires a hardware RAID card.

Thanks! I'll be adding a couple of more Raptors as I get the $$$. I do use Time Machine via a Seagate Free Agent USB external.
