I believe the UPS send signal that can be interpreted by NAS or PC.
Just to be sure better ask the seller.
Your video is in NAS or PC?

nicely written dude. great effort.

been using synology for over a decade and really seen how the product has grown

as for the UPS as long as the USB port with software it should run without any problems, the best use for it is gradual shutdown when batt is low, which means if there is no power to it your NAS will survive until about 3 mins left in battery and get your NAS to be in safe mode. during this time power can cut anytime and won't risk damaging your volume.

you could mount your google shared drive/aka team drive previously and supposedly get "unlimited" storage.

don't think you need plex pass to watch on devices, you only need to pay for activation for IOS think Android TV no need (not sure). but Plex Pass is worth it for this box as you can easily transcode up to 9 streams (hardware transcoding) without any issues (it a freaking celeron chip only)

Everyone is asking about Google photo replacement storage/app. Synology is great but expensive in term of learning curve, maintenance, risk etc. You could setup your own Synology via old pc. Test it out whether its suit your purpose.

Synology has high flexibility.. for typical home users just get D-link ; sync and forget.. may not have tons of feature but for casual users should be enough

Just curious to run 24/7 do we need 4TB HDD above ?

Any HDD sizes can be used for system running 24/7

Thinking of SHR or RAID-5 configuration, of course require at least 3 HDD but will it be less affective compare to RAID-1 when doing recovery later 👉👈

When you link multiple hard drives together to create a RAID-5 array, you create redundant data on the array in the form of XOR parity blocks. These parity blocks allow the array to reconstruct missing data if a single hard drive fails. By performing XOR computations on the remaining drives, the array seems to miraculously resurrect the data from the failed drive. And when you insert a new hard drive into the array and replace the old one, the array uses the same XOR computations to write the data onto the healthy drive.

But unfortunately, there is a risk associated with rebuilding the RAID-5 array. When a RAID-5 array runs minus one hard drive (in a degraded condition), its remaining drives endure much more stress than usual. And that stress only increases once the rebuild process begins and the server must work to both integrate the new drive and continue performing its duties. With the additional workload, a second hard drive in the array might fail during the rebuild, creating gaps and holes in the array and crashing the server.

If use RAID-5, all the HDD need to be in same size. You can add bigger HDD but it can only utilize same space as the smallest size HDD in the pool. SHR would be the better choice if mixes sizes HDD as it can maxed out the utilization.

If recovery, RAID-5 need to constantly read from the remaining HDD to do the rebuild, it create more stress to the remaining HDD.

RAID-1 when rebuild poses same risk as RAID-5 in that if another HDD failure it means all the data will be unrecoverable. That is why need to have multiple copies of backup for important data. 3-2-1 backup rule is always the recommended way. If your NAS data is always being use for read and write/amend, that is not backup, that is just your present data. You need to have at least another 2 backup, and one of the backup is stored in different place.

Nice write up, I have considering between DS920+ and TS-453D.
Just wonder, is this with 4GB of RAM?

also think if under normal scenario like photo viewing, video streaming and simple file viewing, does NVME cache helps.

a friend teach me install 1gb ram = 1 tb disk.
cache = possible hit or miss. no gurantee
