2 ssds for cache

[alex036]

Hi, I have been using a 500gig ssd as my cache drive for a few months, then started to get IO Write errors. I thought it was my ssd failing so i replaced it with a 1tb samsung evo 860.  Now I realize that the cable was probably going bad and thats why I was getting some errors.  Now I want to use the 500 gig ssd for my appdata and system and the 1tb for my downloads.  Being fairly new to unraid how can I achieve this.  Now when I plug in the 500 gig ssd it read it as unassigned.  Can this be done and use the full 1tb for downloads?

If you understand docker volume mapping it is pretty easy and several possibilities. I would recommend the 500G as cache for appdata and the 1TB as Unassigned for whatever.

 

See the Docker FAQ:

An argument could be made for having 1TB cache instead. Depends on how much caching you do.

is there a video on how to use the unassigned drive as a download drive?

Will unraid move the downloads to the array as a rg cache drive?

Unassigned drives are not part of the array and do not participate in User Shares.    It is up to the user to manually manage their contents as they are not part of Unraid’s automated management.
