Tested with the built-in card reader of a Sony Vaio laptop's (via adapter).
Write / Read speeds are correspondingly 7.23 / 10.5 Mbyte / s (see my picture in the product images). At the advertised Class 6 fits into it. Nothing to complain. The reported by other reviewers 13 Mbyte / s I can not get. But no matter.
Also works without hesitation in my HTC phone.
I still have a same card of half a year earlier, also purchased directly from Amazon. Recently wanted a Samsung Omnia 2 Get device tested with the purchase of this first card, it has not been identified. Speaks well against this Samsung device. Just as info.
The fact was that.
