It is normal for a card that's sold as class 10, UHS class 1, to have sequential write speeds of just 7.5MB/s?
I was expecting a something closer to 10MB/s, i.e. Class 10 performance. Or, is it common practice for memory card manufactures to over exaggerate their product's capabilities by that much?
The product in question is a brand new Sandisk Ultra 32GB Micro SDHC card, the only other class 10 card I have manages 9.5MB/s seq. write which IMO is much more reasonable.
Have I got a duff card? How fast are your class 10 cards?
