If you have money for an SSD system, then why not? Also, there is no “no need to modify me for an eternity system” as such. Backups and periodic verification is a must if you want to keep your data. No matter HDDs or SSDs. Also, RAID 1 with 4 SSDs? That’s only 1 SSD usable capacity. Unless you mean RAIDZ1.

Well, that’s a tough question but I think no:) Unless you have multiple backups and want to experiment:)

There should be no problem streaming 4k from HDDs as others said. As to SSDs, depends how long are you going to store them without power but I’d say they will be fine for several moths or even more. Again, backups. Also, I’d run CrystalDiskInfo to check drives health: https://www.pcsteps.com/2530-predict-hard-disk-failure-crystal-disk-info/

How much are we talking about? I mean, Backblaze B2 or Wasabi might be a good option. Or hetzner if you’re in Europe.

Definitely not motherboard RAID. However, why not MDRAID (old but gold) or ZFS (protection against bit rot plus all the other sweet features like snapshots etc.)?

Is boot drive selected in the boot order? Probably yes, but just to check. You can also try using Starwinds free converter: https://www.starwindsoftware.com/starwind-v2v-converter to convert the disks to raw or qcow2.

I’m using an old Synology for backups. But for a NAS, you could build a DIY machine and put TrueNAS on it.

There will be no performance gain even if you passthrough NVMe drives to that TrueNAS VM as you still need connect storage back to Hyper-V (iSCSI or SMB). You’ll just add more latency.

Depends on the price difference. Overall, I would go for a newer.

6s. The best one for me.

It’s a good phone and more convenient for me compared to Android.

Yes, that’s possible and it will protect against a drive failure. But of course, you’ll get the speed of the slower drive. Also, keep in mind that RAID is not a backup.

If you have an old PC, that could very well be a start. Otherwise, Dell Optiplex or Intel NUCs will be more powerful than Pi at the same price. Throw Proxmox on it and you have yourself a homeserver.

TrueNAS needs direct access to drives to ensure proper corruption detection and repair which is not possible with a hardware RAID controller. But if you’re on ESXi, you could just deploy a Linux VM with Plex on a hardware RAID datastore.

Well, as others said, ideally, follow the 3-2-1 backup rule: https://www.backblaze.com/blog/the-3-2-1-backup-strategy/. An external drive plus some other cloud storage like Backblaze Personal or iDrive.

If you can still read it, I would start just manually copying the most important files one by one.

Most likely, the drive is damaged. there should be some local companies that do recovery. At least, it’s worth asking.

As others said, Rclone and encrypt your data before sending. I wouldn’t trust no matter what the cloud provider says.

I would go with Ubuntu Server. Anys OS will need maintenance. Alternatively, Proxmox if you’re into VMs.

And that is awesome!
