Well, I would have thought making your eSATA drive part of the RAID1 array would be plausible....even a good solution. > >> Also, I'd say that plugging/unplugging disks would historically be a >> problem, but SATA shouldn't be, IMO.

I don't think the controller was the concern, though I could be wrong - my take was it was more that the connectors might wear out or something along those lines. Either a removable hard drive chassis or an external eSATA drive would seem to fit the bill from that point of view...
