Never even thought of NAS before google decided to take away free Photos storage. Just need a NAS at home for laptop/ mobile data and Photos back up. 95% of the time it will be one user only. No streaming video or plex requirements. Is 220J good enough for me for the next 5 to 6 years of use at home? Or do I need 220+? Thanks
Yes, for simple file storage and backups Synology J series will be the cheapest option and yet most reliable choice.
DS220+ would be faster and allow you to install more apps without having limitations. But for simple file storage, this could be overkill.
I hope this helps.
