I bought 3 x microSD from SanDisk - 16GB Ultra cl10, UHS-I but transfers while saving or reading is too low i suppose, below attachments:
Photographs of card:
Benchmark in ATTO (with adapter SD with reader SD):
- Kingston 2GB microSD (some older card)
- SanDisk 16GB (in the same SD reader)
- SanDisk 16GB (the same but in another reader also using adapter)
All I want to know is if the cards (from SanDisk) are original or not? Are transfers correct or not? I expected transfers via 20-30MB/s (info on blister) but i have much lower transfers. Somewhere in Internet i found the intormation, that class 10 means that writing on card isn’t slower than 10MB/s, as you can see - something is not ok. Any suggestions?
