For some reason and it wasn't installed on my Debian based MX Linux distro.

I've just installed sysstat, the package it comes in, and I have to Thank you for pointing me to the program

I remember that command from Linux and I've just checked online since I'm on the phone and found this hit

I didn't see that specific switch though

Up to now I have not seen any USB thumb drive which can write as fast as it reads in practicality

The 64 to 256 GB thumb drives that I work with, write at about 6 to 8 Mbps when they are in sync mode

In the beginning the drive seems to lie and shows speeds that are close to the absolute speed of the USB 3 Connection. In reality is not really a lie because the Linux Operating System loves to cache it's file systems, especially if they're native, like ext4

However the file system warns you never to remove the thumb drive until it's actually done writing. If you use something like Midnight Commander it will show you that the writing speed drops all the way down to six to eight megabytes a second!

That happens on both modern systems and on Old obsolete systems with just USB 2
