Have a new QNAP TS-216G delivering tomorrow, and must admit I'm pretty excited to set this thing up and get it running and backing stuff up. I bought a Crucial MX500 4TB SATA SSD for the primary storage, and now am thinking I want a second to fill that second bay and run RAID 1. Can I throw in a Samsung 870 4TB drive or is it best to have matching SSDs in there? The Samsung is actually on sale and the Crucial, that I got for $216 at Best Buy, is now $279, making the difference much smaller in price. Maybe I buy two Samsungs and return the MX500? What are your thoughts on this?

Thanks

Yes you can.
As long as the size and type are the same, brand does not really matter.

But....why RAID 1? What is your other actual backup routine?

I will use MARS to backup the family's google photo albums, integrate with OneDrive (that has far more than just media) so that gets stored on the NAS as well. My intent is to have 3 copies. 1 copy on each of the phones, 1 copy in the Google Photos cloud, 1 copy on OneDrive cloud, and 1 on the NAS. Wait, that's 4. I really like backing stuff up. So if I mirror the SSD, now I'll have 5. Can that be right? UGH

No, the RAID 1 mirror is not "extra copies"
RAID 1 only wards off physical drive fail. It is not really 'another copy'.
The user and OS only sees a single copy of the data. Delete (or corrupt) and it is gone.

When I first set up my QNAP in 2017, I initially ran a RAID 5. Over time, the RAID became less and less relevant.

Now, that little pod of drives has expanded to 3x 4 bay things, 12 drives, and near 100TB usable space.
Nary a RAID in sight.

Geez, I'm pretty sure I have around 2TB.of total data to store. You have much more. Anyhow, do I even need a 2nd drive in there given that I already have it in two cloud services and on the devices themselves? Maybe I'm going overboard.
 
If you at least want piece of mind that you have two copies with you on site, you can do what I do: have an extra drive and make the NAS back up the back up regularly. There's usually a tool in the NAS that lets you schedule this operation.

What would be your recommendation here? Two drives not using RAID at all or is 1 drive enough for backup plan?

There is no one perfect plan.

But generally, 3-2-1.

My house systems back up to the NAS nightly or every other day, as needed. Macrium Reflect.

That NAS volume backs up to another volume attached to the NAS.

My 'off site' is a couple of drives in a desk drawer at work. Refreshed every couple of months.
