Used for irreplaceable documents and data. Reliability is utmost importance. Currently run in RAID-6 configuration. Use for backup and online streaming of music and movies (many home archives over 70 years old). Also, I backup to hard disk (store offsite) and backup to Synology Cloud. Started with 3x2TB disks and grew to its current size. Mainly concerned about age and that Synology will soon put DiskStation into maintenance only mode for this model so I want to go with newer model. Choice seems to be between DS423, DS423+, and DS923+. I'm ok with standard 1G port. All seem very similar hardware except for CPU. Also, how important is ECC in DS923+? What model do you recommend? Also, toying with DS923+ because # disks can be expanded. If I want to upgrade beyond current 8TB useful capacity (with RAID-6) am I better off with DS923+ and adding expansion chassis where I can just add another 4TB drive or should I bite the bullet and upgrade all current disks?
