Synology RS1221+ and RX418 for main personal storage, media and device backups.
Synology DS918 as a backup to personal data on RS1221+
Synology DS423 + Synology TC500/BC500 cameras for NVR surveillance
Synology DS220+ offsite as a backup of personal data.
I like Synology for their ease of use in setting up. I just replaced an older SYnology and IP cameras with the DS423.
