And when you tried to straighten it, it broke off, no? That's been my
experience.

That might be obvious to you, but it isn't to me. You ran different tests in
the two cases, differing in -T, as Volker pointed out.

It is my opinion that benchmarks should be done with a real benchmark tool.
Try with bonnie++
This will really show you the strengths and weaknesses of your setup.
Good luck,

Processing power of the external USB-SATA controller chip could also
come into play. But in your case I think you're getting the maximum
speed possible from the
