I've searched around and come up empty so far....

 

Since my cache died earlier today, I stuck in a temp disc for the moment. I have 2 samsung evo 250gb ssd's available currently hosting a few vm's via unassigned devices. I also run plex from the cache transcoding to ram.

 

Would I see a noticeable improvement in vm performance (for photo editing and heavy nle video ) if I put them in raid 0, vs the default btrfs raid pool? The editor has access to 20 threads for cpu intensive processing.

 

If I did raid 0, I would run a backup every few days of the cache to help with data loss, so i'm not concerned about that. I actually have a 120 samsung pro around as well that I was thinking of using as a scratch drive, but could toss that in the btrfs pool for a little more room if needed I suppose (though I don't need it there).

 

thoughts? I'm not currently buying any other drive for this setup.

Since nobody had any thoughts, I went ahead and set up a raid 0. while some aspects of plex's images seem to load faster, my OS X vm has experienced numerous spinning pinwheels. this never happened with the image only on 1 ssd mounted via unassigned devices. I'm not sure if this is due to the data striping of an os, or from the relatively small amount of dockers I run causing problems. Even Krusader has had a few hangs during operation that I haven't had before. Next week I'll convert the disks to a mirror and see what happens. if the pinwheel goes away, then I'll know it's because the os doesn't like the striping, which it isn't aware of anyways....

raid0 should always be faster than single device, I ran a 8 SSD raid10 for a while and performance was very good.

that's what I would have thought too.... not sure why i'm gettting hangs...
