You don't need a RAID card, in fact don't use one. There is a chance it will overwrite your data. Clone the drives, ONLY work on clones, never on patient drives.

What would you recommend for the cloning side of things?
If the drives are healthy, something like ddrescue does a good job. Cloning the entire drive (even empty sectors) is best.
If the drives are NOT healthy, you need professional data recovery equipment. (Ace Labs PC-3000 or at minimum a Deepspar DDI4). If you have a drive with a physical problem and you try to image it w/o professional data recovery gear, you have a good chance of never seeing the data again.
