running zfs on linux 1.8 RC2 for 4 drives with raidz1 for testing and rsync my backup to test the speed

the writing speed is 55M/s to 90 M/s... it shoot 130M/s for less than 8s at the begining.
reading raidz1 to /dev/null can achieve 130M/s...
the backup source is SSD on USB3, I know can peak more than 130M/s when reading.
this is from cockpit:
5T SMR seagate seems ok-ish,
