thanks.
that's a convenient tool.
however, it keeps producing:
$ bonnie -d /media/tmp/
Writing a byte at a time...done
Writing intelligently...Can't write block.: No such file or directory
Can't write block 478518.
$ bonnie -d /media/tmp/
Writing a byte at a time...done
Writing intelligently...Can't write block.: No space left on device
Can't write block 474393.
i checked the default parameters. nothing seems wrong.
i was benchmarking a kingston 4GB microSD card, connected with a usb adapter.
any help will be appreciated.
