Is there any performance difference between the VMDK and VDI virtual disk formats with Virtual Box?

In virtual box 3.0.2 is there any performance difference between using the native VDI virtual disk format and the VMDK virtual disk format?

"I don't think so - for example, this blog post claims the following:

Both formats are wrappers around a raw
disk image so raw performance isn’t
really at issue.

However, it also says the following:

VirtualBox has to mount a vmdk image as a writethrough disk, which means it loses things like snapshots and possibly driver performance.

I don't know if this applies to the newest version, but it sounds like you should go with VDI."
