How to have SHR on XS series Synology NAS – SOLVED

Last updated on 14 Oct 2021 📧 Subscribe

I can not find SHR option, why some models have it and others do not?

Yes, Synology XS and rackmount models do not have an option to choose SHR as a RAID. Synology do not want to mix different size drive on these powerful NAS because you would not get maximum performance as you would if you used only same type of drives. RAID would work more efficiently and Synology would not need to deal with enquiries asking how to improve performance. But we think there should be at least a choice.

The way to do it is migration. If you have an existing NAS with SHR, after migration you will still keep this type of RAID. Just make sure you can migrate from your model to xs series.

 

 

 

Here is SHR supported NAS models:

  2. There seem to be a lot of questions about whether or not you could do this and THEN add drives to the SHR once it’s up-and-running on the DS1621xs+. I just tested this today for our @MacGeekGab podcast, and it definitely allows you to add new drives to the SHR, just like an SHR-supporting NAS would. No issues. Using DSM 7.2.1-69057 Update 4.

  3. Thank you for this test! Am I understanding correctly that I can put my SHR drives from my 918+ to a 1621xs+ and also add additional (same size) HDDs and expand the volume?

  5. Jesus Christ so what. SHR gives you access to the extra storage on the larger drives you install. When a traditional raid makes wait until all drives are replaced with the same capacity. So one logic makes you wait u til you finished upgrading drives and the other gives you gratification sooner. It’s personal preference. SHR isn’t as stable as the traditional raids. So when you use SHR on a business class raid and you run into problems. What’s going to happen. People will complain and want to be compensated. People would blame Synology and say why would they do this knowing SHR isn’t as stable as the traditional raids. Synology took away the customers ability to screw up their raid and blame them. And you know people would do exactly. Want SHR then buy a lower end NAS. Want a higher end NAS then deal with it. Right here you prove Synology’s point. You want the gphigher end NAS but don’t want to deal with the costs involved with it. Having a higher end NAS but running it with lower performance architecture. Then when it fails you complain. Synology in a way is doing like Apple does by building in a better experience. By wanting SHR on the higher class of NAS proves you don’t want a higher class of NAS. Let me buy a Ferrari that has an high compression engine then complain because I can’t put regular gas in it. Some people are never happy. Thumbs down

  7. Wonder if you could do a part 2 of this video and see what happens when you try to add additional new, larger drives to the volume… Does the SHR accomodate them as a true SHR volume, or does the system treat them as if it were a traditional RAID?
