Finally, I test the card with adapter under Windows 7 on my laptop using h2testw for NTFS and FAT32 format, both of them have the same performance, about 10 MB/s for writing. And I also inserted the card with FAT32 format in milestone, the writing speed is still about 5 MB/s, I did not test with NTFS format.
The card costs me 30 euro, and it functions normally with adapter, so I don't bother to return it. However, I am warning you guys, do not buy SAMSUNG 32 GB Class10 sd card, it can only achieve around 5 MB/s with FAT32 format
