My cache drive data currently sits with just my appdata for a few dockers, mainly plex which is probably 25gb+ now, and my docker image which is 20gb. My plex app can be sluggish when starting up for the first time but I think this is from being spun down/offline? to conserve power? Or could be from my massive library.

 

Currently I have 2 250gb SSDs setup as a raid0 pool. They are connected to my sata 6gb/s sata ports on my motherboard. A couple of things;

 

1) Does having 2 ssds raid 0 in a pool give me a huge performance bump as opposed to raid 1 for redundancy? I was pooling 500gb total for plex and 2-3VMs.

 

2) Can I drop my x2 250gb raid 0 setup for a x2 128gb raid 1 pool instead? The thought being I can now pass-through my ssds for my VM instead of making vdisks.

 

I'm thinking I want to switch to raid 1 pool if its not a huge performance hit for read/write, so that my plex library is backed-up with my appdata. As it stands now if I lost my plex library appdata I would loose over 25gb+ most of which is metadata for my media. I have terrible internet 12Mbps/1Mbps, so it would take ages to try and replace it all.

 

 

Thanks in advance!

It should give a nice performance boot, but you can awlays test and check for yourself if it's worth it in your situation, raid level can be changed with the pool online, see the FAQ

Yes, again see the FAQ for how to replace cache devices.
