Inexpensive RAID1 card required for Linux-drop in-and forget

There are a number of servers I have, that do not have RAID installed.
I cannot easily add mdadm, and create a software RAID on these various servers. (many distros etc.)

I was wondering if there was a inexpensive Linux RAID1 card.
I dont want the RAID card to be another SPOF.
That is, if the RAID1 fails;
I can just connect either of the RAID1 drives back in to the SATA or IDE connectors on the motherboard.

And most definitely, I do not want to "reformat" any of my servers to make a RAID1.(This would create reliance on the RAID card, and that is what I am trying to avoid)

I would hope the Rcard would work as a RAID1 with as little modification as possible.

You are pretty much just SOL on all counts. Good Raid cards start at about $300. Raid is always (at least every one I have seen) specific to the card. I have also never seen one that you could just unplug a drive and read from a "regular" port. You do understand that even with Raid1 you need to backup you drives on a regular basis?

I disagree with you dismissing the option of mdadm. Its free, can be deployed on many servers quite easily, and easily portable between linux systems. If you still don't change your mind I recommend any cheap RAID0/1/10 card with an sil3112 chipset.
