I did manually designate the location because I wanted my VMs to run off of an SSD. I guess I just didn't fully understand how UnRaid worked under the hood.
So, in order for it to work as I want it to I need to have my main VM vdisks run from the cache drive and there is no way for them to each run off of their own SSD? Maybe, unless I use multiple cache drives, which I'm sure is not recommended?
After I move the vDisks to the cache drive, should I then remove the 3 SSDs from my array and possibly just take them out of the system completely?
