I have a perdicament. I will have a total of 16 3TB drives with maybe 4 more on the way to round out my norco 4020.
The research I did shows that doing a raid-0 like setup with a bunch of raid-1 volumes is best for random io. But that cuts my usable space in half. I don't need that kind of fault tolerance.
I was thinking 4 disks in a raid-z aka raid-5 if I am thinking right. And then take those raidz volumes and make them into a single raid-0 setup. Is this fatally flawed?
My usage consists of about 4-6 users doing all sorts of things like streaming movies, backing up their albums, accessing said music, compiling from source (one of my VMs will be gentoo probably).
Also, I have a 32GB X25-e I'd like to put to use as a cache if possible. I figure that will limit me to 19 disks as I'll have to use one port for the SSD, I'm using the PCMIG backplane from one of the articles.
Thanks,
alex
