Thank you for clarifying.  

I've been trying to wrap my head around RAID and your points helped a great deal!]]></content:encoded>

                        <content:encoded><![CDATA[I want to occasionally use an External Startup Disk (Non-RAID).

However I am unclear what the implications might be to my external SoftRAID RAID5 when I boot from an alternate external startup.  

My RAID 5 is, of course, not configured as a startup disk.  I typically boot from the computer’s built in SSD and store most of my data on the external RAID 5.

I am concerned that booting from an alternate boot drive might break or corrupt my RAID 5  … OR if the external startup disk will simply ignore the RAID 5 altogether.  I’m reluctant to try before getting clarification.

The alternate external boot disk will NOT be a clone of the internal boot drive.  Instead it will be streamlined and not be configured with SoftRAID.

I do NOT need access to the RAID 5 when booting from the alternate external drive.  I suppose I could simply switch off the RAID 5 enclosure when using the alternate drive, but if I were to forget to do so then what might I expect.

Please advise what, if any, precautions I should take to ensure that my RAID 5 is not broken or corrupted.

In an alternate scenario … If I did want to access the RAID 5, I assume I would also install SoftRAID on my alternate boot drive.  And If I did so, then would that pose any risks to the RAID 5’s integrity.  What would I need to do to ensure no problems might occur and that all remained in sync?

I’m sure my scenario is a typical use case, but I’ve been unable to find solid guidance.  I want to avoid any unnecessary headaches.


I’m using the following:
- iMac Pro
- OS X High Sierra 10.13.6
- OWC Thunderbay Thunderbolt 3
- SoftRAID XT with RAID 5
- Alternate External Boot/Startup Disk TBD (likely SSD)]]></content:encoded>
