This is a place for all topics regarding Synology hard- and software - especially (but not limited to) their NAS devices.

Just one thing: Let’s please be pleasant to each other and respect that people have different experience levels. Some are pros, some are noobs, yet everybody may have good ideas or interesting questions to ask and comments to make, and all of these shall be heard and appreciated. ❤️

And since we know from TV that all IT nerds 🤓 are h4xx0rs and wear hoodies all the time (if not even ski masks) in front of their computers, I chose an appropriate banner image (image credit).

How do external drives behave in relation to internal NAS storage/management? (www.synology.com)

Not sure the best place to ask this.

I have a DS420J 4 bay NAS, primarily used for my Plex server and data backups (among a few other things). I currently have 8x6x6 TB Iron Wolf NAS drives in a single volume with SRH and an extra 1 TB SSD JBOD. I have my Plex app and metadata stored on the SSD due to the increased performance I have seen vs. having it installed on the large pool (7200 RPM cap). I am sitting at about 85% used storage of my available 10.8 TB on the primary volume. As such, I am pre-planning my next storage upgrade and am curious about my options while staying with the current hardware. The future plan will be a NAS upgrade, but this little beast has been chugging along so perfectly I want to push it as far as I can.

If I was to remove the 1 TB drive and replace it with another 8 TB Iron Wolf, I would jump to 20 TB available storage. https://www.synology.com/en-us/support/RAID_calculator?hdds=6%20TB%7C6%20TB%7C8%20TB%7C8%20TB This increase would last me for quite some time ahead of a full NAS upgrade with more bays. In order to do this, I would obviously need to remove the 1 TB SSD to be replaced by the new drive. I have na external enclosure for this drive that can connect over USB to the NAS.

My question: I am finding somewhat conflicting information on how external drives are intended to be used/what their capabilities are when connected to the USB 3.2 port. It seems the intended functionality for backups (which makes sense). Am I able to utilize a USB connected drive and have it function in a similar manner to it being internal? Are you able to install apps from the Package Center to an external drive? Create volumes? I assume there will be some performance degradation due to the translation from SATA to USB, then back to SATA, but I anticipate the SSD will still perform better than adding the app back to the main pool. I just don’t know if I am potentially missing something with my evaluation. Those that have more experience with USB connected drive with their NAS, I would love to hear your experience. Thanks!
