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:
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).
Is there a tool in Linux to measure speed vs time or speed vs space usage?
