Raid Flash Drives With USB 3.1 USB HUB?

I would disagree - it can be done, but you won't be able to RAID it under Windows. You would have to RAID it under Linux/MAC. There was a video out on youtube on the subject. This was limited (if I'm not mistaken) to a USB 2.0 system. A USB 3.1 system would be significantly faster, especially if you used a RAID5 or striped setup.

I wonder if you could create a MDADM RAID10 setup under Linux using the NTFS file system, then put it on a Windows machine and see if it pulls up (Win doesn't support RAID5 until Win8.1(?)/10)
