It will work until the part of connecting the HDDs with the RAID already created on another system. Creating the raid from CTRL-I is the best step you can do to create a volume but if you disconnect those drives and reconnect them on another it is possible that raid will be shown as failed.
This is because the RAID volume was created with information from another system; however, there is a chance it may work if the other computer is exactly the same brand and model.
