yes, he gave me the same tip, before that I hat 1.8mb (!)
since my cpu is faster than yours I should easily reach the 10MB/s and more.

the dd command takes max 5% cpu load while doing  the test

well you know wether it will speed up later on ? Its ok, unless I have 
to reformat, I dont have the means to backup 700gb of data just like that.


thx for your comments anyway !
