2019 Mac Pro with M.2 PCIe-based Flash RAID Carrier Boards

December 31st, 2019 by rob-ART morgan, mad scientist

With 16 lane PCIe 3.0 slots, the 2019 Mac Pro accepts advanced PCIe- based flash RAID cards. How fast can they transfer data compared to the 2010 Mac Pro?

WHAT DID WE LEARN?

The 2019 Mac Pro with its 16 lane PCIe 3.0 slots takes full advantage of the speed that PCIe 3.0 M.2 RAID cards offer.

We included the test results for the Amfeltec and Sonnet boards installed in the 2010 Mac Pro's 16 lane PCIe 2.0 slot to emphasize how the 16 lane PCIe 3.0 slots in the 2019 Mac Pro unleash the full potential of the M.2 PCIe 3.0 RAID boards with fast PCIe-based flash modules.

Some readers have asked about using the RAID volume as a macOS boot drive. I am not a proponent of using a RAID set for that purpose. Apparently neither is Apple since the macOS installer refused to continue.

You could stripe all but one of the M.2 modules and use the remaining one for a System volume but then that degrades your transfer speed since the two volumes are competing for bandwidth.

Finally, for those unfamiliar with ATTO Disk Benchmark, here's what the resulting bar graph looks like.
