also one more observation:
when i execute this command on exos i am getting 50MB/s
root@truenas[~]# dd if=/dev/ada1 of=/dev/ada1 bs=1m status=progress
203423744 bytes (203 MB, 194 MiB) transferred 4.010s, 51 MB/s
253755392 bytes (254 MB, 242 MiB) transferred 5.008s, 51 MB/s
1777336320 bytes (1777 MB, 1695 MiB) transferred 35.003s, 51 MB/s

comparing to ultrastar where i get 100MB/s

root@truenas[~]# dd if=/dev/ada0 of=/dev/ada0 bs=1m status=progress
407896064 bytes (408 MB, 389 MiB) transferred 4.001s, 102 MB/s
10794041344 bytes (11 GB, 10 GiB) transferred 104.005s, 104 MB/s

any idea why its slower by ~ 50MB/s ?
