The drive (c7t2d0)is bad and should be replaced. The second drive (c7t5d0) is either bad or going bad. This is exactly the kind of problem that can force a Thumper to it knees, ZFS performance is horrific, and as soon as you drop the bad disks things magicly return to normal.
Problem is the OP is mixing client 4k drives with 512b drives. They may not actually be bad, but they appear to be getting "misused" in this application. I doubt they're "broken" per say, they're just dramatically slower than their peers in this workload. As a replacement recommendation, we've been beating on the WD 1TB RE3 drives for 18 months or so, and we're happy with both performance and the price for what we get. $160/ea with a 5 year warranty. --eric -- Eric D.
