After my previous 32gig MicrosSD has given Samsung for some reason her mind, I have decided to send this card from Transcend and am thrilled: This is about my 15th micro SD card and my 4 32GB Micro SD and by far the fastest. With my standard reader (Delock 3.5 inch) the card at 20 files @ achieved with large files around 15 MB / s 900 MB) for writing and 19.5 MB / s read - about twice as fast as the Samsung Card I previously had (also Class 10). Can the card fully recommend!
