The retail packaging is different than in the picture. It is red, even here it is "Premium" and "class 10" and "microSDXC" and "up to 45MB / s" and the Roman 1er for the UHS-1 standard is also on it but it can be found in addition, the specification "300x" in the packaging. Also we find the exact type designation "TS64GUSDU1" on the back. "Made in Taiwan" - so everything seems alright.
Performance is great - with exFAT or FAT32 format almost identical: ATTO provides Bench32
Read up to 38MB / s
write up to 19MB / s
This is very good, though not the fastest UHS-1 card date (SONY SF16UY, a 16GB standard-size card that plays technically in the same league, also 300x, but write to 27MB / s).
Anyway: The card has now been described in the endurance test over 6 hours, deleted, described, deleted, etc. - fits.
64GB in FAT32 (Software: MiniTool Partition Wizard 8), so that even what with it my old COWON D2 + (MP3 player), even if the card for such a player from a performance point strongly "oversized" is.
My Full HD camcorder with 50p came completely without jerking the map clearly, ie Full HD Video Cam is applying for the card.
All Samsung Smartphones / Tabs have the card without hesitation recognized and used as an LG smartphone.
Conclusion: Performance in absolute green area, price cheaper than in DE, no compatibility issues running ... what more could you want? Very satisfied.
Update 4/2014: Map is actually over, all data could be saved but the Broken effect is interesting. Map can read and it can be saved. Card can not be formatted under Win8.1. Although a Transcend own tool formatted "allegedly", the process goes through without an error message, a "Success" message is issued at the end but the card is simply not formatted, because all the data are still present. The generally accepted reference formatter "SD Formatter" reports do: Card is write-protected (it is not :-)
Update 6/2014: I have the card at Transcend complained directly. Response was something like this: If you can not format the card with the SD Formatter, it is defective. Although the card is purchased through Amazon.es, I got an RMA number, then have the old card, including adapters returned and got in exchange a brand new. Great service - thank you to Transcend.
Short Test (card as shown, so the red-black version)
ATTO provides Bench32
Read up to 38MB / s
write up to 21MB / s
... A little bit faster than the old writing.
