I checked the numerous threads and none of them mention this… I need a eSATA card that works on my '09 Mac Pro w/ 10.6 Server. Needs to have 2 ports or more; bootability is not important. What it must have: OS X 10.6 64-bit kernel support. Port multiplier capability on both ports (or at least 2). Good reliability and performance. What I can also do is replace my existing RAID card (Areca ARC-1212) with another card that has eSATA on it along with the internal ports. Thanks!
