As stated in other posts, looking into getting some new hardware. Is there any real noticeable difference between NAS-labelled drives and surveillance-labeled drives? I'm going to have a couple extra bays, I'm considering getting some extra drives to dedicate to surveillance station, but was curious if I should be looking at the surveillance-labeled drives, or if they are even compatible with a Synology NAS. I did some googling but never really found any good answers so I came back here.

I’d say yes. They are designed for continuous writing. The price difference is not much.

You can go for something like the WD Purple and have them in their own volume configured with ext4 (not Btrfs) file system.

4tb looks to be about the same price on Amazon. Any reason to not just buy all surveillance drives and put the videos in the same volume as regular storage? Could then use the extra drives for more storage capacity/redundancy. What's the advantage to ext4?

It is a recommendation (not needed ofc) to use EXT4 with the volume dedicated to SS tasks. But again, it will work on btrfs as well. Details in the KB

The surveillance drives –as I understand it– are tweaked for constant writing (because that’s what your cameras, via SS, are doing most of the time), while the regular drives are designed with a read/write performance balance.

What's the advantage to ext4?
Performance. ext4 doesn’t have the Btrfs overhead (e.g. checksums). If you end up with a glitch (in the Matrix) spanning a few seconds, for a home user, it’s not a big deal 😁

I guess both you and @Rusty have alluded to my problem with finding an answer in google: yes, there is a difference between the drives, but will I as a home user notice a difference in drives/format big enough to matter? From what I've gleaned here and elsewhere, there is an advantage, but it probably won't be big enough to matter to me? Right now SS is only recording motion events. If I set it up with its own drives/volume I'd probably set it to record constantly and only send alerts on motion detection.

For your convenience use it as you wish, if you start having problems (you shouldn’t if recording occurs briefly during motion), you can always change things. Nothing is cast in stone.

I have SS running on a BTRFS capturing motion events. No problems for years (even before on an older 412+ model).
