[Disk priority setting / balancing for speed]

I'm just starting to experiment with DrivePool, and I'm wondering how best to use it to optimize for speed.

 

I've got the following disks

SSD 256Gb boot/OS

SSD 512Gb working drive - photography 1st tier

 

HD 4Tb fastest - photography 2nd tier tier

 

HD 1Tb ok - replication / read cache

HD 1Tb ok - replication / read cache

 

HD 2Tb slow - archive

HD 2Tb slow - archive

 

For the moment I'm just using drivepool for the spinning rust disks... and will use Samsung RAPID for my working drive - so that's out of scope for now.

 

The rest can be in the pool - but by default

* when I save something into /pictures into the pool I want it to hit the fastest 4Tb drive first (then replicate in the background or overnight to one of the other drives - I guess I don't mind which one, but would prefer to keep it to the 1Tb ok speed disks)

* when I store something into /videos, this system is only a long term archive (as the files are AeroFS copied to my media server; so here I want it to drop to one of the slow HDs)

 

I think DrivePool optimizes for space first; and doesn't know that the new 4Tb disk is the fastest... which is a pity...

 

So should I simply set balancing to set

Pictures to use ONLY the fast 4Tb drive (unless I run out of space)

Videos to ONLY use the slow 2Tb drives (unless I run out of space)

 

Thoughts?
