Upgraded my 2010 Mac Pro to Mojave. With a $10 million NVME to PCI Express card, I was able to use it as a boot disk for my 9 year old computer. According to the Black Magic speed test, I got over 1500,000 reads, with the SATA SSD 300 and with the WD Black 136. The fastest SSD isn't necessary since the PCIE bus on the Mac Pro is only 2.0, but it is so still great.
