Welcome to LQ
I am looking for a eSATA card that is well supported in Linux. Particularly, I am looking for an eSATA card that works with a linux driver and can handle NCQ. (NCQ should allow the card to operate fast. My card/driver combination apparently does not handle NCQ.)
I would recommend the Hardware Compatibility list, www.google.com/linux
and emailing businesses with your linux question. Support businesses that answer questions. I do that, and it simplifies life.
also if there is a better place, even another site, to be posting linux/hardware
related questions, i would be happy to oblige.
Some folks would take that as treason, but we won't shoot you this time ;-). I note you've been posting it elsewhere as well, but we won't shoot you for that either.
To judge by a quick look around, ncq is still bleeding edge. It's often wiser to let a technology develop before using it unless you want to be involved in sorting it out. It's only an advantage for servers, and not, I gather with seagate drives or via chipsets.
