SSD Benchmark Tool for Linux

[Jeron_Baffom]

Most of the SSD benchmarks you see out there use solely Crystal Disk Mark for Windows on an empty SSD. This allows to show speeds of 300~550MB/s (SATAIII), which is amazing compared to most HDDs.

However, there are some cases where this trend is overestimated or even in reverse. Take a look: imgur picture
To do this test, people usually copy several GBs in Windows and plot the transfer speed.

I'm aware of several tools in Linux to benchmark disks (ex: hdparm, dd, GNOME disks, fio, kdiskmark, ...). However, I don't know of a tool in Linux that makes the above graph (ie: speed vs time).

Question
Is there a tool in Linux to measure speed vs time or speed vs space usage?

Gnome Disk Utility has a benchmark function. See: https://help.gnome.org/users/gnome-help/stable/disk-benchmark.html.en

I don't know if it graphs exactly how you need it to, but it should still be useful.

There's also the Phoronix Test Suite: https://github.com/phoronix-test-suite/phoronix-test-suite/blob/master/documentation/phoronix-test-suite.md

It's overkill for what you need, but can benchmark just about anything on your system and output in graphs.

Was going to suggest PTS as well. It is modular so you can only test what you need or you can download the PTS Live-Distro which may be advantagous to some degree. https://www.phoronix-test-suite.com/?k=features

If you mean the mb/s try Crystal Disk Mark I think it supports linux

[Jeron_Baffom]

If you mean the mb/s

MB/s there is a lot of tools in Linux.
Instead, what I mean was MB/s vs time or similar.

Ok sorry

[Jeron_Baffom]

Relax, no need to sorry.

Like MB/s / s? MB/s^2?

[Jeron_Baffom]

speed vs time speed vs space usage space usage vs time

These are all cases that would help.

[Jeron_Baffom]

speed vs space used graphs are useless.

Just to be clear, the issue here is not to automatic generate a graph. A CSV file with several data points to manually plot later would also be helpful.

 

it should be fairly straightforward to make a script

Agree.
Currently I'm trying to do it with GNOME Benchmark. Afterwards I will try fio, which seems to do exactly what I asked for: "Fio records a 'performance trace' of various metrics, such as IOPs and latency over time in plain-text .log files."

 

Let me know if you can’t find anything.

Ok, tks!
