I was using an onboard AMD SP5100 raid controller for a Raid 0 on two 1TB drives. The motherboard has failed. I have two questions - firstly if I replace with an identical motherboard, will I be able to get the Raid 0 intact? Secondly is it possible to recreate the raid in software. The output from fdisk and mdadm are below

Will I be able to recover the data intact from the RAID 0 on a different RAID controller? – kevinl – 2017-02-12T11:41:41.560
Yes as long as the controller supports Raid 0 which it most likely does you can recover the data same with software raid. – Frostalf – 2017-02-12T12:32:12.757
