I have a desktop system which unfortunately has only two SATA channels, which are used by my primary and backup HDs. I would like to add a particular DVD re-writer which only comes in SATA. Is there an add-in card or something similar available which I can use to allow a third SATA connection?

Since the backup HD is used only occasionally to make backups (yes, I know, I should do it more regularly) I guess that I could leave the one device plugged in most of the time and just switch plugs when the other is needed, but I really don't want to do that. Is there such a thing as a SATA switch?

Thanks for any ideas you may have!
