This is What 42 Peripherals Daisy Chained to a 2013 Mac Pro Looks Like
(MacTrast)
Macworld connected 36 drives (19 Thunderbolt, 15 USB, 2 FireWire 800) with a combined capacity of 100.63TB. They also connected two Thunderbolt docks (the Belkin Thunderbolt Express Dock and the CalDigit Thunderbolt Station), an Apple Thunderbolt Display, two Apple Cinema Displays, and one HP Z Display Z27. WHEW!
A dozen of the drives were powered directly via the cables connecting them to the Mac Pro, the remaining 24 required external power. The combined power draw when running a script that copied data from the Pro’s internal flash storage to the external drives was 865 Watts.
The Mac OS X Activity Monitor showed that there was a combined throughput of 3 Gbps. The rate slowed as the fastest drives, (OWC’s Mercury Helios), finished transferring data.
