zdb is still running, I'll edit the rest of the results in later. It is taking forever.
I am actually considering replacing all 8 drives with different drives. I have had way too many issues with these and I'm actually kind of fed up. A bunch of them also have a really high load cycle count and will probably need to have the warranty used still. (I've had to warranty 4 out of 8 of them). I'm in Canada so I have limited drive selection - mainly ncix.com, newegg.ca, and canadacomputers.com. I can't find the exact drives you mention but I could get WD Caviar Blacks. Do they have any ridiculous settings which would be problematic for RAIDZ, or would they work well?
edit: Just got back from the store, bought 8 Western Digital Caviar Black (WD2002FAEX) 2000GB (2TB) SATA3 7200RPM 64M Cache (OEM). I'm going to start replacing all of my drives one at a time
I'm running 8.0-REL still. I've never done an upgrade of FreeBSD. Is it reliable/stable to upgrade both the OS, and a ZFS pool? Not losing data is the most important thing to me.
