# dd if=/dev/zero of=/dev/sdb bs=1M oflag=direct
dd: error writing ‘/dev/sdb’: No space left on device
979+0 records in
978+0 records out
1026555392 bytes (1.0 GB) copied, 185.655 s, 5.5 MB/s

So no media errors in both commands.

I used fdisk to create a partition, and created a vfat filesystem.

Same lag. Took 1 minute 20 seconds from sdb1 being recognized, to
udisksd mounting it.
