Has anybody tried an AKiTiO Thunder2 eGPU with a Thunderbolt hard disk daisy chained or on a Thunderbolt second port? I'm really interested in any reports of the performance impact and stability implications- read entire thread so hope I didn't miss any! I don't really get how x4 PCI-e 2.0's 16 gigabits of bandwidth gets muxed by the controller into 4 TB channels, are they counting the bandwidth of the display portion or something? Any of the reasonably priced HDD's I'd be considering are bus powered and appear to be TB1 only: Get info about the cutting-edge portable Thunderbolt drive by Buffalo I'm running with a late 2013 rMBP 13", and would be going the ATX PSU-only route. Cheers!
