Wasn't this data already available on another disk or device? If that's the case that's your back-up
Make sure it is RAID 1 when you rebuild it. Forget about the Hybrid Synology RAID since you have only two disks. SHR starts making sense when you have more than 3 HDD. Hope that helps. And keep in mind that however annoying the first steps are, once this is set-up, not much else to do. Just rip and save on the NAS and enjoy the music.
