I'm not convinced this is a good thing -- I think you should have to know that you're attaching an SD card and not a hard disk, because the performance is much worse. In particular if you don't specify 'cache=writeback' your performance will be dreadful, so you need to do something different from hard disks anyhow. -- PMM
