Steps to Upgrade Internal Storage Drive in Nucleus

Why not leave the SSD alone and obtain a NAS to store music? If you set up the NAS in a RAID5 configuration you would have some failure tolerance which you will not have if you store everything on a local SSD. I have more than 1.5TB of music. I would hate to lose it all in a drive failure. Just saying…

RAID is not backup…


It’s more backup than storing everything on a single SSD. I use a NAS with RAID5 and then copy everything in real time to another NAS and then to a USB drive that is hanging off my NAS. Just to be really careful I also use a cloud service to back up everything in real time as well. So you are right that RAID is not backup. But no backup is not backup either. I was not advocating for RAID as a backup. In my posting the exact words I used were failure tolerance. I never used the words backup.

…but the NAS experience is pretty miserable compared to the SSD inside the Nucleus. Even USB spinning drives are better than the NAS experience.

@Gerald_Schrader – your plan is mostly good, including the last step.

I would modify it slightly:

  • insert a “logout” as step 1.5
  • then restore from the login page in step 8
  • swap steps 4 and 5

Why? I have been using a NAS for my Core and for all my storage for over two years without any issues or problems. What is it about a NAS that has been a miserable experience for you?

Using a NAS as networked storage, compared to an SSD inside Nucleus:

  1. it’s another device to manage and set up
  2. it’s another failure point in the system, far more likely to require repair or maintenance than a non-moving SSD
  3. network storage doesn’t auto-scan in all situations, and network storage is notoriously dependant on great networking
  4. NAS tend to be noisy (fans and spinning drives) and power hungry solutions (another cpu, etc…)

While they do work, it is my opinion that a NAS is an inferior solution.

If you require fault tolerance, there are silent and less power hungry USB RAID enclosures.


Understand your points and they are obviously good ones. This has not been my experience using a NAS. I am actually pretty happy with my situation as it is today. Maybe someday I will look at it differently. For now my application works well for me as does the application that you recommend. I just feel as if I am better protected from mayhem than I would be with a one drive solution.

Danny, thanks so much for the assist! When you say swap steps 4 and 5, I assume the point is to stop the server software before formatting the new SSD?

yes, itll speed things up and not screw around with the db on ssd… its not a critical swap, just better.

John, thanks for the suggestion. I have considered a NAS many times, and while I may get one in the future, as long as my music collection will fit on an internal SSD in the Nucleus, I would prefer to stick with that configuration. It’s silent, takes up no extra space, is cheaper than a NAS, and requires no management work. While a RAID 5 configuration offers drive failure tolerance, a friend of mine had his RAID 5 NAS fail recently due to a motherboard failure in the NAS, so they’re not a 100% fail-safe solution.

In addition to the SSD inside the Nucleus, I have my music backed on two separate hard drives inside my PC, on an external USB drive attached to my PC, and also in Cloud storage. So a SSD failure in the Nucleus is not going to put me out of business.

Danny, with your suggestions, the correct procedure should be as follows?

  1. Backup Roon database.
  2. Log out of Nucleus.
  3. Shut down Nucleus.
  4. Remove and replace storage SSD with larger one.
  5. Power up Nucleus. On web admin page, stop the server software.
  6. From web admin page, format new SSD.
  7. Copy music files across the network from my storage backup location (PC) to new internal SSD in Nucleus.
  8. From web admin page, restart server software.
  9. Go to Nucleus log-in page and restore database.

Am I correct in assuming that by restoring the database, I also avoid the lengthy process whereby Roon scans each and every music file for audio level info?


That all looks right and you are correct on the scan.

One question, what is your PC and can it read EXT4 partitions?

It’s an older home built PC with an Asus Z68 chipset motherboard, an Intel i7 2700K CPU, and 16GB of RAM. It’s running Windows 10 Professional. Google tells me that Win 10 can’t read EXT4 directly but it’s possible via some third party software?

Reading is possible with the utilities I know of, but, not writing to it.

As a side note, if using external storage exFAT is usable on both Windows and ROCK.

I’m not sure where this discussion is going - are you guys suggesting it’s possible to copy the contents of the old SSD to a new SSD by connecting them both to a PC?

No, not suggesting that at all. I was just providing extra information relative to your comment. And as an aside, I was making a comment about external storage and common usage formats between Windows and Rock, again as a side note.

Sorry for the confusion - I’m just kind of in the dark as to why Danny asked me if my computer could read EXT4 partitions. Regarding your comments, I assume the implications are that you could format an external drive as exFAT, attach it to your PC and load it up with music, and then plug it into the Nucleus (as an alternative to starting with the drive attached to the Nucleus and then copying everything over the network)?

I have an external drive load up on windows PC plug into NUC. I dont copy to an internal drive, I keep it on the external.

i asked because if you want to read the old internal ssd and copy it to the new internal ssd over the network, you will need to be able to read the internal ssd’s contents from your pc

what sizes are these 2 ssd’s you are coming from and going to?

Seems like an import from external drive/folder to internal storage on nucleus/rock might be a feature request worth persuing.
