Re: [opensuse] 12.3 + ntfs + ext4 + USB3 + different copying speeds

And so....what has been resolved? Anything?
Nothing - Greg has seen that copying ~1000 large files from NTFS to NTFS over USB3 can be done with decent IO-rates. You're seeing something quite different when copying <something> from internal SATA to NTFS over USB3. That you get such different results probably warrants digging a little deeper.
Rather interesting that nobody with any "inside knowledge" about ntfs-3g is put together has commented or made suggestions as to why there are such differences in the transfer rates - especially in the light of what is written in the wikipedia (which I quoted).
It is rather unlikely that anyone with inside ntfs-3g knowledge is listening in. If you want to get the bottom of this, you need to start by eliminating/reducing the variables. Hardware differences - comparable disks? Only copy files with 'dd' using a fixed blocksize. Copy the same set of files - similar to Gregs if you want to compare. Reformat the target partitions every time you do a test.
