I have available a single usb 2.0 port and a single usb 3.0 port and would like to set up two HDDs (both usb 3.0) in RAID1.
Not entirely sure how mirroring works, but was wondering if there was some way I could configure the drive connected to the usb 3.0 port to serve as a 'primary' drive of sorts that would be prioritized for 'initial' writes/reads in order to maximize performance, with any data being copied to the drive connected to the usb 2.0 interface.
Any ideas or suggestions are welcome. Ideally the solution would work for an OS compatible with the raspberry pi 4, however, I would be interested to learn of any other solutions as well. Thanks in advance.

The reading speed limit imposed by USB 2 caps out at about 8 MB/sec for USB2, and 20 MB/sec for USB3; writes will be worse.
