You can offload some data to external drives. Just make sure they have a backup or RAID protection just in case. These USB connected drives will not expand your NAS storage and you will not have access to this data in a normal way via mapped drive (only via DSM admin panel).In meantime, you can add any drives you to your NAS. It will work. It is just recommended to stick with the same kind of drives due to performance purposes. Simple file storage might not need this though.I hope this helps.
