TS-473 QTS 5.2.6.3195
I have the opportunity to update to QuTS-Herio, but am not sure if it’s worth doing. I’d like some real world experiences and recommendations please.
Many thanks
I have your NAS’s bigger brother, the 873. I converted it to QuTS Hero. There are advantages and disadvantages to it.
The ability to have WORM folder is absolutely terrific. You can set the folder to have items remain in WORM mode permanently or have it expire after a certain period of time. Really nice feature.
The include compression and deduplication features are great too. It definitely helps with saving disk space but it does come at a slight performance penalty.
I haven’t conclusively proved this but I think the ZFS format does take up more drive space as it seems after moving to Hero I had less space left on my RAID arrays.
The biggest difference to me between the two OS’s is in creation of shared folders. In QTS, you create a shared folder in your volume and go on your way. In Hero, a shared folder is considered its own volume. This is advantageous as you can set the size of each shared folder, set the block size used, compression, deduplication, etc. It’s just a bit more work to do and it is a bit of a shift in the way you think about your shared folders, how to allocate space, etc. Let’s say you have 20TB of storage. In QTS, you create 10 shared folders and they all share that 20TB of space together. In QuTS Hero, you can create 10 shared volumes each with 20TB of space! The system will let you do that. Obviously, you can’t fill up 200TB of data but it allows you a very flexible way to look at your storage. You can make multiple volumes have access to the entire space while others you can limit.
I’m very happy with the move.

Thanks again. Do you lose any of the othe functionality that QTS provides, Containers, Virtualisation etc?
Nope. You get all of that.
Expanding volumes is not as flexible. QVR Elite costs more than QVR Pro. ECC memory is highly recommended.
What do you mean by the reference to QVR Pro. QVR Pro works fine in QuTS Hero.
Hero on the NAS only works with Elite. QVR the Viewer (windows, Android, etc) works with both…
That used to be the case. That is why I went with QTS because of the 8 licenses.
What do you mean that used to be the case? QVR Pro runs on QuTS Hero. I have run it on Hero. So I don’t know what you are saying.
The QVR Pro was indeed not work with QuTS hero before, and it only started supporting it with QVR Pro 2.6 at the end of 2024.
We know that QVR Pro feels attractive because it comes with more free channels by default, but the QVR Elite really shines when it comes to performance and how it handles file storage.
The team is working on making future updates cover the best of both, so users can enjoy solid support whether they’re running QTS or QuTS hero.

Hi @pzh20 the early versions of QuTS hero did have fewer applications, but that should mostly been resolved now. If you still notice something missing, please let us know.
The main difference from QTS is the ZFS file system with WORM support, plus features like deduplication and compression for saving space and more. Because of this, QuTS hero needs at least 8GB RAM, and 16GB even 32GB is recommended for smoother performance.
Switch to QuTS hero requires system initialization, it is worth try when doing a new setup. But if your QTS is already running well, I…recommend staying with it.
The choice between QTS and QuTS hero really depends on your specific needs. For example, for heavy multimedia usage, we would recommend QTS.
For a detailed comparison and explanation, you can refer to this link: QNAP QTS (EXT4) vs QuTS Hero (ZFS): Choosing the Right File System | QNAP (US)

I tend to go by the philosophy if it isn’t broken don’t’ fix it… That is me.
Well, that’s true but it depends on if you want or need the features in QuTS Hero. If you want WORM then QTS is effectively “Broke” as WORM doesn’t exist in QTS.
Pros:
Dedup and compression.
Zfs is more reliable and recovers/rebuilds faster after drive failure.
Worm option
Cons:
There is no caching and tiering on hero.
I found spindle drives much more active on hero compared to quts.
Slower with low number of drives (rotational)
QuTS has ZIL and ARC cache, so the no cache info is wrong
