Upgrading to PR4100 from PR2100 and have some questions!


Hi Everyone. It’s been 9 months since I purchased my PR2100 for using as a plex server & a personal NAS.

In that time I’ve become extremely keen on not only the interface but the WD brand and this NAS’s capabilities when it comes to transcoding. Today I purchased a PR4100 (Diskless) to upgrade from my PR2100 (no reason, just future proofing).

What my question is…

  1. can I simply remove my existing JBOD drives 2x3TB WD RED and place them in the new system?
  2. Are all my apps stored on the drives or on the hardware?
  3. I’ve read recently about people using SSH to check various things, how do I access SSH? (I know how to turn it on).

Thanks guys!


Yes. A “RAID Roaming” message should appear on the dashboard after inserting the drives… one at a time. The message is somewhat misleading in the case of JBOD drives, but following it’s instructions should allow the drives to be integrated within the new enclosure.

It depends… User-installed apps are stored on a hard drive system partition, and other built-in apps are contained within the firmware, which is stored within the hardware eMMC system partitions.

Accessing SSH can be accomplished using a variety of different methods, depending on the OS and personal preference. To avoid problems, always use the NAS IP address when connecting.

From Windows, I tend to use the Putty program most often. From a Linux environment, I simply use the ssh command and standard syntax. Replace user with the login username, and xxx.xxx.x.xxx with the NAS IP Address.

ssh user@xxx.xxx.x.xxx

For those who don’t know how to enable SSH, it can be enabled from the Settings/Network section of the dashboard. It’s disabled by default and must be enabled before use.


I appreciate your reply as it’s proved helpful.

As my new bay supports 4 drives (and I currently own 2) is it possible to install my current 2 as JBOD and set the other 2 up as RAID (whichever RAID I choose). Eventually I plan on getting rid of the 2 JBOD drives and adding them to the RAID whenever funds allow. I’ll be looking into buying 4 x wd red 10TB over time for the NAS


I believe it may be possible, but I’m not sure because I only use JBOD volumes. Experience has taught me that using RAID in NAS boxes is a very bad idea, and that using JBOD volumes with a sound backup strategy is a much better approach.
