Question about SanDisk Ultra Dual Drive M3.0

I have carried out a few measurements with HD_speed and get a stable read rate of 33MB/s for the 64GB variant. The write test showed values of 15MB/s. In addition, a large .iso file was copied from the NAS connected via Gigabit - about 15MB/s transfer rate. The NAS otherwise achieves a good 110MB/s.
It would be nice if others also published their values.
