What a good two port stata raid 1 pci controller

I agree with Preston

Just not sure a raid card would work well on a PCI bus.
32bit PCI bus has a peak transfer rate of 133
MB<http://en.wikipedia.org/wiki/Megabyte>/s,
probably good enough if not many things are using the bus.
?

But, again probably, not enough if you want a fast raid 0. I mean, use raid
1, but one partition with raid 0, which can be done with mdadm (software
raid), and not if you use the card raid controller (not allways, at least).

If I was looking for a good (hardware raid) card, I'll look for PCI Express.
Or PCI-X, if I had the slot.

PS: I have no experience with raid cards, other than the embedded to turn
them off :)
I think good ones are too expensive for my needs.

At this time (again, for my needs) I'll probably spend the money on 1 (or 2)
SSD.

So, jgarciaitlist at gmail.com :)
why do you want a pci raid card?

Regards
Luis
