Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

I built my 10ish TB (usable after raidz2) system in 2015. I did some drive swaps but I think it might have actually been a shoddy power cable that was the problem and the disks may have been fine.

I had a Helios that literally just started having trouble powering SATA disks a few days ago. I got it in 2019 I think, so only 5 years of life.

I use Linux LVM and either ext4 (for older volumes) or btrfs (for newer volumes, because I want the checksums across the data) so in principle I could throw the disks in a PC as a temporary solution.

I have put the disks in SATA to USB 2.0 caddies, and the Helios 4 kind of still works, but I'm ordering a couple of Orange Pi 5 and with USB 3.0 disk enclosures to replace it. It was kind of time anyway, since Nextcloud has dropped support for 32-bit CPU.

Both DS220+ and DS224+ has been a pleasure to setup, but I wouldn't replace your DS218+ just because. Just make sure your RAID is healthy and your backup too.

An alternative to a standalone NAS is to setup your own little ITX server. Only if you enjoy tinkering though, Synology is definitely easier.
At home I'm currently running Server/NAS/Gaming PC all in one.
It's a Debian 12 KVM/QEMU host with an m.2 NVME disk for host OS + VM OS and 2x16TB Seagate Exos disks in RAID1 for data storage. The other hardware is a B650 ITX Motherboard, AMD Ryzen 7600 CPU, 2x32GB DDR5 RAM and AMD Radeon 6650 XT, Seasonic FOCUS PX 750W PSU.
With my KVM/QEMU host, Game Server and Jellyfin Server online it eats about 60W-65W, so not that bad.
The GPU and an USB Controller is passed through with VFIO to a virtual Fedora that I use as a desktop and gaming client.
Just make sure to have a sound dampening pc case so you can keep the servers online without being bothered. The GPU goes silent when the gaming VM is off.

It'll last long as it's useful to you barring any disasters. I've got a HP gen8 microserver that I've been running as a free/truenas box 8/9 years now and I'm only thinking of replacing it now as I need more performance than the CPU in it can give.

Ah, I see you also choke yours with softwarr...

I have the same model as you and I also wonder when it will explode lol (mostly because I have it in my ROM and can hear when it is struggling).

I have it with lots of docker containers (I can't help it, it is my only server) and the drives never cease to spin.

I actually don't recall since when I have it but it must be similar as you as well...

Just as of recently started to do clean up of containers and such, mostly because I did a fuck up (I deleted with Portainer all my unused volumes which, strangely enough for me, got rid of Portainer's volume, I needed to recreate all my stacks/compose from portainer each one, so I cleaned up some stuff in the process).

Had my Western Digital My Cloud since 2015.

At least 5 minutes.

oh you are dancing with the devil. not sure there's a way to check actual SMART data in Synology's OS but I would be very interested in those logs.

I've found over the years that the second I think about backing up the drive is about to fail.

I would update to a 4bay and invest in actual NAS drives. (and I will personally be looking for 10gbe lan but this isn't homelab)
