What people need to realize is that rolling your own data storage solution increases the risk of being hacked, losing data due to disasters, or losing remote access to files due to stupid crap like a router dying. If you're just using a NAS to store your porn, then that's fine. You'll just torrent the files back again. BUT if you are talking about pictures from your childhood, business files, or other critical documents, you seriously need to consider if you have a sufficient backup policy with off-site storage, and if you're going to be disciplined enough to update your disaster recovery plans.
I used to believe in rolling your own solution, until Synolocker came out. It became clear to me that Synology had no idea what it was doing with regard to security. I finally gave up and move my data over to Google Drive for Work. Sure, I'm giving data over to evil Google. BUT, I have access to my files anywhere with Internet access; I have two-factor authentication with the FIDO U2F app; I have a copy of the files on my computer as well as a backup in the Google cloud, which is pretty much a million times better than anything I can cook up.
I also don't have to worry about hard drive failure, updating firmwares, etc., etc.
