Cache configuration opinions/help

[marvin888]

I am completely redoing mu Unraid server and have some questions about cache configurations.

I have:

1-1TB NVME SSD

2-used 400GB (Intel DC S3700 enterprise SSDs)

1-250GB SSD (Samsung 840 evo)

1-180GB SSD (Intel 520)

1-128GB SSD (Crucial M4)

I Will be using unraid mainly for network storage, Plex (mostly local network streaming 4K, possible transcoding) and the *ARRS. I want to get into some tinkering with linux in VMs.

 

I was thinking:

Cache 1 - 1TB NVME SSD - app data share, plex meta data, VMs and VM disk drives (I feel like these app/VMs would benefit form the speed)

Cache 2 - 2 400GB intel SSDs (mirrored) - *ARRS share, media share (I feel like *ARRs will have a lot of read/writes but don't need nvme speeds. plus save the HDDS from spinning up all the time.

Cache 3 - 250GB DDS - all the other shares.

use cache 2 for app data share and plex meta data?

should I use the 400GB Intel SSDs separately? Cache 2 and 3

 

How would you set up the cache pools and shares usage? how would you setup the cache setting and mover? I will be using cache backup app saving to a not cached share.
