Hello Chris! It's great to hear that you've been following our channel and have decided to go for a Synology NAS based on the software they provide, especially the Active Backup for Business app for multiple device backups and bare metal recovery. Among the DS1522+, DS1621+, and DS1821+, these models already boast robust hardware that can last for at least 10 years. While there might be potential replacements for the 21+ models in the next 12 months, any hardware upgrade won't significantly impact the tasks you plan to use the NAS for. So, you can confidently choose from these models to meet your backup and recovery needs without the need to wait for possible updates to the 6-bay or 8-bay variants.
