The card reached me only a write speed of about 8 MB / s in a Transcend card reader who has already 20 MB / s write. On my Digisol card reader reaches only 7 MB / s. Reading them is much faster with about 25 MB / s (Transcend) and 18 MS / s (Digisol).
Overall, I find the card's performance rather weak, cheap class 4 memory cards from SanDisk were significantly faster at me with 12 MB / s Schreibgeschwindikeit. Overall, I feel that the quality varies strongly with Transcend, have yet measured at identical memory cards have significantly different speeds, also is heavily dependent on the speed card reader. SanDisk cards are as much steady.
