I went ahead and added all the drives of concern to unRAID, as well as a single new drive. Regarding the moving of data into unRaid, I did the same as Taddeusz above. I guess if you don't set cache only then if you have space issues on the cache it'll move things to the pool? I didn't do any special configuration and those things are on my cache SSDs. It seems like unRAID defaults seem to push VMs and docker data to the cache. So, if you wanted all your installed apps to be on SSD, you an just creats an "appdata" or "apps" share and then set it to be cache only, and then all the data for those apps would be on SDD.įor Docker, my docker images are all only SSD, but, docker images don't store their configurations in the image (or else you would lose it when docker images get updated), so typically when you are configuring a docker image (like sagetv), you have to tell it where on the unRAID system it can store it's configuration/appication files, and that share can also be a cache share, if you want. A Cache drive is generally 1 or more SSD drives. When you create a "share" you can say which drives it can use, and whether or not it will use a "cache" drive, and whether or not it will ONLY use a cache drive.

I know that unRAID uses a USB drive for the OS, but does it make sense to use a SSD for the partitions where SageTV and other applications are stored? I know that moving to an SSD years ago on Win dramatically improved performance.
