I have a Synology 8-bay 1817+ from 2017 with 8 - 4TB WD NAS drives setup in RAID 10 for data safety. I’ve had this connected to a UPS the entire time (swapped batteries, etc) and it gracefully shuts down if there is a power outage. Everything is reporting normal, drives SMART data looks great, device is operating well. I also have redundant offset backups of the data.

Given that most HDDs only last ~5 years on averages, should I begin replacing the WD RED NAS HDDs eve though they are operating fine? Feel like I’m on a ticking time-bomb. Has anyone had any experience upgrading/migrating a Synology from one set of drives to another?

Thanks

    This depends only on one factor. Do you have backups?

    How long the drives are operating is meaningless. The variance on the average HDD life is so huge that failure from lifespan is impossible to predict.

    If you have proper redundancy and backups there’s no reason to replace any drive, unless it’s actually having issues.
