This is probably correct, but doesn't specify the actual write speed. Take for instance SanDisk's 4GB microSDHC card. The one I have is a class 2, but I can get sustained reads of 9.5ish MB/s (not Mbit), and sustained wites of about 3.8 to 4 MB/s (again, not Mbit). So, yes, the card complies to a class 2, but it definitely outperforms it. I wonder if this is the norm or if it's just another good product from Sandisk.
