I'm up for upgrading again. I have an external drive that's currently running on FW800, but I have too many FW800 drives, so instead of daisy chaining all my drive, I wish to run said enclosure via eSATA. Unfortunately I have run out of PCIe slots. My decisions is to replace the Areca ARC-1212 I currently have with something with eSATA on it. It needs to be bootable obviously. Maybe if I don't have to rebuild the RAID that would be even better. Any recommendations? Basically the cards I have: GTX 285 in Slot 1, Areca ARC-1212 in Slot 2, USB 2.0 card in Slot 3, RAID battery in Slot 4. Yes I know I can remove the battery, but that would make my RAID-5 risky. I don't want to just double stick the battery somewhere. I could remove the USB card, but I'd run of USB ports.
