Thank you Ztcoracat.
There is a slight problem.
None of these tools actually make it possible to test read/write performance on the disk as a hardware part in full GUI. Meaning that i could simply do *click click click testing read write -> output*. They still ask for a short command line or they can't test the r/w at all. but thank you for the support.
But! the good news is that i currently found a tool called udisk/udisk2. this tool would make it possible to "benchmark" read and write speeds of hard disks. and the Gnome-Disk-utility would make it possible to do it in full GUI with just clicking!
Here is the "bad" part. when i try running the command udisks (udisk/udisk2 command), it gives the output: udisks-WARNING **: Couldn't connect to system bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
If somebody on the forums would have any idea how i could fix this. It would be VERY much appreciated.
Thanks for the time, Sincerely rootict,
PS: new to forums in general and very new to Linux forums. please correct me if i do something wrong
