You are wrong.
Under the hood copying in linux works following way. Every time you read something from disk the file information will stay cached in memory region called "buffer cache".
That is true - on a mounted file system. Writing directly to a block device (like /dev/sdb) does not use the buffer cache in any way.
Is there still no raw device on Linux?
