Hello everyone,

Currently I have an unRaid setup on an HP Gen8 MicroServer that has 4 x 3.5 WD Reds as data & parity discs plus single 2.5 250gb Crucial SSD as the cache drive. I use that single cache drive for download files to and where I've got my docker apps & app data installed. 

I'm building a replacement for the Gen8 with the capacity to add more 3.5" drives and I've also gone for a new Mobo & CPU as I want to run one or two Windows VMs

My new Mobo (ASRock X570M Pro4) as NVMe support, so could anyone confirm if I'd be better off getting a decent NVME SSD to put the docker apps and app data on and leave the 2.5 SSD purely as a download cache?

I'm thinking about a 1tb NVMe drive - possibly a WD Black.  Would this be the best approach and any SSD drive recommendations would be welcomed.

If I do go down this route I guess it's fairly straightforward to move the existing apps/docker directory to the new drive?

Thanks in advance
 

I assume you mean to create another pool. The SSD and nvme would need to be different pools to get Unraid to use them separately. Mover won't move files between pools, and nothing can move open files, so there are a few steps involved getting dockers/VM moved to the other pool, but not difficult.

And of course, you will need to backup files that won't be moved to the array.

Yes, I think the correct terminology is to have a 2nd cache pool - so 2 pools, one with the 2.5 SSD and the other with the NVMe SSD
I'm not to precious about anything downloaded to the cache pool but not moved to the array being lost but any VMs and their associated data I'd wanted backed up.  I presume I could keep a backup of the NVMe apps and appdata folder on the array itself? (just manually backup every so often)

There are plugins for that.
