MPG has a 1TB Apple SSD in the Mac Pro, and a 1TB SSD in the iMac 5K.
Disk I/O speed is the culprit.
Mac Pro: writes at ~930 MB/sec and reads at ~1180 MB/sec.
iMac 5K: writes at ~716 MB/sec and reads at ~766 MB/sec.
The flash drive in the iMac 5K is a two-lane device. With each PCIe lane delivering 500 MB/sec but with ~20% overhead, peak speed is thus limited to ~800MB/sec (theoretical) for the iMac SSD (the Mac Pro allocates 4 lanes).
Or iMac 5K or iMac Pro?
