I did something similar, but with a SCSI drive. I keep a large external USB drive as a
"last ditch" recovery pool which is synchronized hourly from the main pool.
Kind of like a poor man's tape backup.
When I enabled dedup=verify on the USB pool, the sync performance went south, because the USB drive had to read stripes to verify that they were actual dups.
Why did you set dedup=verify on the USB pool?
