Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ).

Synology 8-Bay - Time to upgrade HDDs? (alien.top)

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

I second that 5 years seems a bit low. I have a backup NAS that has 10 4TB HDDs, half of them are 8 years old. I will be replacing these soon just for the peace of mind. They still seem to be working just fine. In fact, in the last 10 years, I've had two HDDs fail, they were a 4 TB Seagate NAS and a 3TB WD Red. The first was DOA and did not pass preclear tests, the second one died within the first three years.

P.S. I remember that I bought a couple of 2TB WD Greens for a ridiculously low price (I think it was $60?) before the floods hit the factories ages ago. They all worked flawlessly 24/7 for almost 10 years, I ended up retiring them for peace of mind. Definitely did not expect them to last so long, being the cheapest choice at the time.
