we want to know - How fast can a single storage volume read or write, in Megabytes per second
for example - 125MBps throughput.
so we used the smartctl command in order to capture the XXXMBps throughput. value
but we not found this info from smartctl
any other options?
smartctl -a /dev/sdb
smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.10.0-514.26.2.el7.x86_64] (local build)

This...
$ lsblk -ap -e7 -o NAME,MOUNTPOINT,FSTYPE,LABEL,RO,RM,STATE,TYPE,SIZE,MODEL NAME MOUNTPOINT FSTYPE LABEL RO RM STATE TYPE SIZE MODEL ...... will give a nice table over available devices (excluding loop:s).
Pick one thing from the NAME column and use as $dev here...
sudo hdparm -Tt $dev
Oh, and you need this:
$ sudo apt install hdparm
