Right now I'm using my old HTPC (GA-MA78GM-S2H, AMD Athlon™ Dual Core 4850e.K @ 2500, 4GB RAM) as my first unRAID server. I got 2 WD Red 8TB disks, and not using any parity drive.

 

Mostly I use the server to be able to stream my media to LibreELEC htpc over a gigabit LAN, but also running Transmission on the server (and I plan to use MySQL, FlexGet, CouchPotato and stuff like that).

 

I'm think to use a SSD for the cache (since that's what I've heard is a great thing to do), and I wonder is a 80GB is big enough, or if even a 128GB SSD is big enough? What I understand is that if I got a SSD, the drives could be spinned down more than they are now, since that the SSD will be used during the download until the torrent is completely downloaded? Is that right?

 

I use settings in Transmission that the files are downloaded directly to the path I want, with the .incomplete at the ending, instead of downloading to something like /download first, and then moving the file. Does that in some way interfere with the main purpose of a SSD for me?

 

Also, what happens if I download a torrent that is 200GB big?

 

Thanks for the help.

Be sure to check out those other links at the top of that wiki for more about how cache is used on V6.

80GB would be rather small for a cache drive used for Dockers.  I'd view 128GB as a more realistic minimum and 250GB is where most people start off.  Obviously, it depends on what you do with it - you might need something bigger, or smaller.  I've got a 20GB Docker file and find it's easy to accumulate stuff in appdata, though.
