Totally agree on cloud redundancy.
I lost considerable amount of files because of a bad drive.

It would be based on the DiskStation DS418j plus 6TB HGST drives.

On the other hand, I just ordered a couple of 2TB SATA SSDs, so those might fit the bill for my desktop PC for the moment.

Any suggestions or tips for setting up a home NAS?

For the RAID setup, you can use the RAID calculator to know how much usable space you need, it is on synology website. RAID5/SHR is enough for most usage. You can make it RAID6/SHR-2 if data is important, you lose 50% capacity that can survive 2 disk failure.

Thanks for the tip! I'll be going with RAID 5, and just back up my critical data daily on external SSDs. I'll just be using a 4-disk array, so space would be at a premium.

Ideally I'd have another NAS on RAID 10, but I'd likely do this only when my critical data is about to go over 2TB.

Yup just look up the model of your NAS. RAID 10 is for performance, are you going to run write intensive application?

Yes, a small local database with high availability and redundancy. I may even try storing some games, if the performance is acceptable

I'm thinking of getting the Synology DiskStation DS418j which should support most common RAID types.

Hehe my fantasy and sci fi book collection alone is 1tb . Downloaded over the years from an obscure site. And yes some of these are digitized comics so the file sizes are heavy. Though most of them are just novels in MOBI or PDF or Epub formats. Cant read them all which is a shame.

I noticed that heat is the biggest enemy of hard drives and the associated electronics. My drives are all piled up on top of one another with their power supplies all spaghetti like beside them. A mess if you ask me. Thats probably the reason for their high mortality and failure rate.

Ideally i would have a proper rack for them. But thats going overboard.

This might help. I saw it browsing through Lazada. It's a simple enclosure, USB interface, no RAID, no software. Just plug and play. I think it has cooling fans at the rear.

The downside is it makes your external drives a lot less portable, not to mention the hassle (remove the individual enclosures, fitting them to 2.5"-3.5" adapters, etc.)

Interesting though you have a point about removing existing drives from their current enclosures. Will take a pic of my messy setup later.
