Since you’ve already maxed out RAM (32GB) and tested SSD caching, it does sound like QuTS Hero is the main bottleneck on your TS-464. Hero is ZFS-based, which adds a lot of overhead, especially on a CPU like the Intel N5105 in your NAS. While Hero has great data integrity features, it’s more suited to higher-end NAS with powerful CPUs.
A Few Options to Improve Performance:
Switch Back to QTS – Hero is heavy on system resources, and your workloads (Plex, Roon, backups) don’t benefit much from ZFS. Moving back to QTS (Ext4) should significantly improve responsiveness.
Optimize SSD Usage – Instead of caching (which doesn’t help much in your case), use the SSDs as a dedicated separate volume for your apps and your Roon database. This should speed things up a bit.
Upgrade to a More Powerful NAS – If you want an upgrade, the QNAP TVS-h674 (i3-12100) or TVS-h874 (i5/i7 12th Gen) will fly through your workloads while still supporting Hero.
Alternative: Asustor AS6804T?
It’s a great NAS with an Intel Core i5, but Asustor’s ADM OS isn’t as refined as QTS/Hero. If you’re already comfortable with QNAP, it might be better to go for a higher-end QNAP model instead.
Best Recommendation for Your Budget (£1500):
Short-Term Fix: Switch back to QTS and optimize SSD volumes.
Best Upgrade: QNAP TVS-h674 (i3-12100) – A major performance boost while keeping Hero.
Futureproof Beast: QNAP TVS-h874 (i5/i7 12th Gen) – If you want unmatched Plex/Roon performance.
