ATA RAID question

I have noticed that the 3ware 7000 series ATA RAID controllers are
listed in the release notes, as supported by the twe driver, but they
are not listed in the twe man page.

I am looking into purchasing a 7506-8 card for use with RAID5 (with a
minimum of 5 or 6 drives to start), and I haven't seen it mentioned in
the recent posts to this mailing list in a RAID5 context.

Has anyone actually used such a card in a RAID 5 configuration?  Is it
bootable under FreeBSD?  Any caveats?  The drives will most likely be
120G Western Digital drives, with 8M cache.



Another (non-FreeBSD) question related to this card:  The 3ware.com site
lists this card as "PCI 2.2 compliant 64-bit/66MHz bus master".  Would
this card work in a 32-bit/33MHz PCI slot (at least until I also get a
new machine to put it in)?  My main concern here is reliability, not
speed, but I don't want to waste half of the capacity on a mirrored
configuration.

Any suggestions for other cards that would work with FreeBSD in the
6-drive RAID5 configuration I'm planning are welcome.

Thank you
	Alex
