H2testw reaches permanent transfer rates when writing 15MB / s and read 21 MB / s. That's very neat. The copy of individual files (MP3s, etc.) has an average of 7MB / s works (Windows 7 and card reader). But that's normal, because in 7000 files (3.5GB) many smaller were also there. Here actually break all SD a card. In daily operation, but is not a problem as the transfer rate for video recording completely aussreicht, and more the phone is the limiting factor. In some large files (videos) the speed is so much higher.
