Go on, I dare 5 stars

I ordered 2 units.

The card is pre-formatted (exFAT). Empty, it displays used 59Go (the classic disappointment with the formatting before you can use the storage units).

The screenshots of the benchmark results (dubbed tests) have been uploaded in 4 "customer image".

The rates are good:
ATTO (2 times and stably):
- Reading at 45MB / s (MB / s): this is better than what is displayed seller Skybear
- Writing 19,4MB / s: this is slightly below the 20MB / s displayed by the seller
Crystal (50MB chunks):
- 46 MB / s read at best
- 19.5 MB / s write the best

2 copy large files (1GB) via Windows 7 64bit:
- 13.8 MB / s (SATA HDD to the microSD)
- 136 MB / s (effect hides ??) and stabilization to 74 MB / s in the direction towards the microSD SATA HDD ==> is dazzling !!

It's very honnorable.
[...] Specifies that to receive UHS1 name, you need a minimum write to 10MB / s.
Here I have the double bench and 12MB / s in real life with Windows and various files. This card UHS1 deserves its label.
That is undeniable.

This in itself is good perfs for a microSD Class 10 (this is my first UHS1)
I do not venture to say that it is a contrefasssson. In any case, the very perfs up to the seller's promises and in the absolute.

PS: I just benché 2nd card.
Awesome: I have the results to match those of the first card, via the 2 bench tools.

** The remaining doubts are: robustness in time: do not lose data and do not it rip me in one month **
I repost within one month if it becomes lost or HS data ...
