Looks like sysbench, fsmark and the others pretty much test the performance of the fs.

What tool did you end up using?

I have tried a couple, and am still evaluating. Right now, I am doing some testing on windoze with chkflsh, and then moving to slackware to do a gross speed test, using dd. This way I can classify drives for R/W speed.

For linux, I have played with bonnie++ quite a bit. Sysbench testing has started. But the jury is out, because I will look at all the packages that cyent mentioned. I don't know how he found them. Obviously I need to enhance my searching capability because I missed those.

I am having some problems with the USB interface shutting down, and am chasing that snafu in a different thread.

The first result of my testing will be to identify the two USB sticks that I will be putting on my DD-WRT router to act as simple NAS. Since they can be reached from outside, I can use that as a buffer with the outside world for ftp, with less risk than ftp inside my network.

That is probably more than you wanted to know.

Thanks for the update and the details.

Sorry to hear your having issues with the usb interface shutting down.
Hopefully that will get solved in the thread you made for it.
