I planning to get a synology ds418 for file storage. Just got one question if the nas device few years later faulty can I move all hdd to another synology nas without losing any data? I got a lot of important data which I can't afford of losing it.

you mean I can swap all my hdd to a new any model of synology ex. from a faulty Ds418 to Ds718 without losing the existing raid array and data intact? Just swap without any further headache configuration?

Thanks for yr reply. Lastly izzit worth to upgrade to synology ds418 compare right now i'm using my old pc as a storage server. Hw spec amd fx4300,4gb d3ram, 4x4tb raid5 using motherboard raid.

Last time pc build is easy. Because amd raid i migrate hdd from 1motherboard to another new board without losing the raid array and data. AM2 to AM3+ very simple. Now amd new AM4 hardly u can see raid5 mostly 0,1,10. My storage been running few years already before become data storage . Scare hw might not last in few more years
