For performance, we looked at HDD-only using two 14TB Western Digital (WD141KFGX-68FH9N0) HDDs. However, if you need faster read/write performance, use SATA SSD drives as an alternative. Random read/write performance is significantly improved with SSD, although bandwidth would be capped by the dual 1GbE connectivity. Increasing memory from 2GB to 6GB should also improve overall application performance and multitenancy, and will come in handy if you plan to leverage many of the background Synology apps. In our large-block sequential test, the DS220+ had 223MB/s write, and 231MB/s read in SMB, and 222MB/s write and 231MB/s read in iSCSI, saturating the links to the 2-bay NAS.

Power Protection: I paired my 920+ with a cyberpower SL 750 VA. I use it only for the NAS and it recognizes it without issues. Estimated run time is 70 mins and it has 12GB of ram and fully populated with 4 TB iron wolves. I have it set to start down safely long before the battery runs low.
backups : if you use this as primary storage for family photos and things you don't want to loose. Then I would look into a cloud back up solution Synology C2, Backblaze B2, or others. At the very least I would set up hyperbackup to an external hard drive via USB. Yes the raid helps to protect against drive failures but if the Nas unit dies or is stolen the back ups will allow to to get your data.
Security: if you access these remotely definitely look up videos on options on how to secure them as best as possible for remote access. There was a recent widespread attack on these if people left default settings in place. Wundertech YouTube channel is a great place to start.

The Synology software supports multiple OneDrive logins so you basically can set up 6 1TB backup locations.
Works amazingly well. I never log into the OneDrive app itself. The Synology client handles it all.
Also, thank God for Amazon extended holiday return. Paid $295 for this a few weeks ago when my old ass Synology died and I couldn't be effed to fix the psu.
Ive been running plex off my pc but thinking about making the switch to this.
Also, is there a way to backup to a remote synology? ideally I'd like to backup theirs to mine (once I set it up) and vice versa.

This is cheaper than last November and with the 18GB of memory is a great and very capable NAS (See post #12).

Repeat after me: a NAS is not a backup. Yes if you use two drives in mirrored mode, your files will survive a single drive failure. But your files will not survive an accidental deletion or overwrite. Nor will they survive your 4 year old trying to flush the NAS down the toilet. Nor ransomware encrypting everything all files it has access to. Nor your house burning down. You still need to make a backup of any files you have on a NAS. Ideally a backup would be (1) offline (to protect against ransomware and accidental deletions), and off-site (or on a cloud service) to protect against the house burning down.
So what's the point of having mirrored drives if it doesn't protect your data? It's for redundancy. If your business would lose thousands of dollars per hour that its file server is down, you'd put them on something like a NAS. If a drive fails, the NAS keeps chugging along serving the files while you run to the store and buy a new drive. Pop out the dead drive, pop in the new drive, let it rebuild, and your file server is redundant again.
If you don't need redundancy and just want the safety of a backup, an external HDD you occasionally plug into your computer may be enough to suit your needs. If you need a file server that's on 24/7, a lot of routers have a USB port that you can plug an external HDD into. It won't be super-fast or powerful enough to do things like transcoding. But it's probably enough for 95% of people. (You can do both - external HDD plugged into your router for serving files, another external HDD you plug into your computer each week to backup the file server.)
The main reason to get a multi-drive NAS if you don't need redundancy is to get more storage from a single device than you could from a single HDD.

You can abuse this to swap in larger drives. So if you originally set it up with 2x1TB drives (mirrored), you can later remove one drive and replace it with a 2TB drive. The SHR will rebuild and copy the files on the 1TB to the 2TB. When it's done, you can remove the other 1TB drive and swap it for a 2TB drive. And the SHR will rebuild again duplicating the contents of the first 2TB drive to the second 2TB drive.
Not really the most efficient nor safest way to do it, but it's an option if you need the NAS files to remain available while you upgrade drives.
So dropping from 200W to 100W is a big deal. From 100W to 50W not so much. 50W to 20W might be worth it. But 20W to 10W is probably a waste of money (it will take you several decades for the electricity savings to make back the upgrade cost).
I'm still running a home-made NAS on a 2012-era Sandy Bridge i5-2400. With 4 HDDs and a SSD it uses about 35W at idle. I've been tempted to update it to newer hardware. But the drives make up about 20W of that. The CPU is only about 15W idle. A newer CPU could drop that to about 5W, but that'll only save me $25 in electricity per year (I'm in California where electricity costs closer to 30 cents/kWh).

Or do I have to backup my 4 terabyte Nas to my 12 terabyte external hard drive then plug these drives into the new device format and then move all the data back?
For anyone who uses backblaze is the data totally encrypted from my Nas as I have some personal information some banking stuff personal pictures excetera excetera excetera I want to make sure that's nobody at backblaze can see my info
I tried running it in a VM locally another machine and it's not powerful enough to work properly
I can backup files from my computer to it, therefore it's a backup. I can also backup one NAS to another (in another part of the house, town, country, world), therefore it's a backup. I can also use both of those as well as backup to offline, say USB drives.
Within in an NAS the drives can be setup as mirroring to develop some fault tolerance/redundancy, but yes those aren't a backup, just a way to have some redundancy within the NAS. If all the files are just on the NAS and a person is hoping mirroring drives is a backup, it's not really helpful and puts all your eggs in one basket.
I'd back up your data to an external usb hdd regardless before any migration.
