What is the purpose of separate SSD drives for the Unraid cache and Docker app data? I don’t think I’ve seen that mentioned in other build threads.
Its just to keep the Docker App Data separate from my Cache Pool. I guess theres no real advantage, it just allows my cache to deal strictly with files destined for the Array and prevents the constant R/W to that drive. If you are running UnRaid 6.9, you can just use a separate cache pool for your dockers though.
The guide is here: [Guide] Move Your Docker Image and Appdata to an Unassigned Drive (DEPRECATED)
You also note a 10TB drive as a download/unpack drive. Is that separate from the main array? I’ve been running Unraid for a couple years, but haven’t gone down the rabbit hole far enough to understand why this would be beneficial. (or even how to do it, ha)
It is separate from the array, its an unassigned drive. This is just to keep the files I am downloading/unpacking/seeding from being written to the array. First it keeps them off of the cache drive, second it prevents the array from spinning up whenever there is seeding/downloading activity. Also these files are generally short term storage so I don’t need them to be included in parity and I didn’t want to write them to the array and then delete them constantly. I just feel better having a separate drive dedicated to downloads rather than just having a user share for them.
I just map the path to the drive for all the necessary dockers. Just make sure to select the RW Slave option when you do.
