This seems to be always the case, writing a large amount of data to vdi/vhd is much much slower than writing to a vmdk disk.
I am using the the vboxddu.dll code, and clone physical disk to virtual disk.
for example, clone 250G takes about 2.50 hrs to a vmdk file, whereas it takes 4 hrs to a vdi file, under exact conditions, quite reproducible. There is only writes to disks, no reads.
