Edit Reason: added vfat results for comparision
)
One think to keep mind is that my board was one of pre-production samples, and I had to remove some of the ESD diodes as the wrong ones had been installed on the USB3 connector. Therefore my USB3 performance specs may not reflect the production model performance. And I certainly don't think this is the case, because my USB3 JumpDrive test subject didn't reach anywhere the below read speeds of my desktop in comparison:
rock64 /w 2GB, running Ubuntu Xenial ayufan 0.2.5, against an ext4 formatted cheap Lexar 16GB S75 USB3 flash drive. Write performance is nothing special, but I have had real world 100MB/s read speed from it on my desktop.
Lets see what difference mount options make - ext4 with nodiratime and noatime mount options set:
A comparision of the previous results against the lower USB2 port (ext4, same nodiratime, noatime mount settings):
And to show how the filesystem has a big impact on the results, here is the same test again, but with the drive formated as vfat.
And finally, a Seagate 4TB Expansion drive (mains power external hard drive) (actually got some high numbers this time).
Code:
