Update, the host caching on azure is inconsistent, over a restart we lose the write speed, now I recommend using
Standard D32s v3 (32 vcpus, 128 GiB memory) with IO 768 MB/s or Standard D48s v3 (48 vcpus, 192 GiB memory), IO 1.2 GB/s
Also is better to use gpt as a table partition parted -s /dev/sdf u % mklabel gpt mkpart primary 0 100, and for the disk is recommended is no use caching and select P20 or P30 in a 5 striped array disk.
With P20 disks the average speed is 530 MB/s
With P30 disks the average speed is 650 MB/s
