Why would anybody even have a need for OMV on Raspberry Pi?
It only has USB 2
It's onboard NIC is only 100mbps
You can only get 300mbps using a Gigabit NIC thanks to the USB2 limitations.
I imagine even the AC wifi is limited to about the same throughput.
Your only full speed storage option is an microSD card, which at it's best is slower than a platter.
So again....Why?
I would seriously pull my hair out if I had to wait for 300 megabits per second transfers. Remember HDD/SSD and SD are all rated in Mega Bytes per Second. Each Byte is 8 bits.
I am one who appreciates other point of views, so this is simply a curiosity question and not meant to insult anyone. I am looking to learn what I am missing?
This stuff struggles on an i7 when it comes to OS loading, which is the main reason for my curiosity. Of course I enabled ZFS and burn up 13GB of RAM while transferring, so this further puzzles me that a 1GB device could work at all. I don't run linux on 1GB even in a vmware environment. It can be done stripped down...but OMV is not what I'd call stripped down. Every store bought NAS I've ever touched was a complete let down, and they seem to have similar specs as a Pi3B.
