Any of you guys know of a PCIe card that will do

I have found some, but they are way to elaborate,
and as such, way too expensive.
Maybe you have a weird hardware requirement that explains the question,
but why do you want a RAID-1 card? Software RAID is much cheaper,
faster, uses less power and is considerably more reliable. If you run
BTRFS or ZFS, then it is also easier on the drives, and recovery times
are hundreds of times lower than what you can do with hardware. That
translates directly into hundreds of times better reliability numbers.
Best of all, you do not need matching drives or drive sizes to implement
RAID-1. For a long time now, the only reason to run hardware RAID has
been underneath back-level versions of Windows or VMware.

Hi John,
I am working with a customer's motherboard where
iRSTe is defective. So I just want to chuck it and
get hardware RAID,
Otherwise, you are correct.
