smartctl + how to found the XXX MBps throughput on disk

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
