The map (and I have / had mitlerweile very many) is the fourth fastest that I have measured on the same laptop so far:
Test with h2testw V1.4
Write: 14.6 MB / s
Read: 20.4 MB / s (faster is not the laptop with me)
for comparison: an 8GB microSDHC card class 6 comes here to 17.7 MB / s - an exception for class 6, a 16GB microSDHC Class 10 creates eg 18MB / s.
Nevertheless, for 32GB class 10 the promised specifications are met, almost 15 MB / s is already pretty fast, which - clearly - with large 32GB so has its advantages, one wants to fully describe the same card.
A similar card microSDHC same manufacturer in class 4 Quality would then cost about 30 cents less. This is quite clear: The card is based on class 10 currently compared very favorably.
What you want to ask for more from a reputable manufacturer? Whether it is in five years still works show up, but as long as I do not want to wait with the Rezi.
Purchase recommendation
Update: new laptop determined by ATTO Bench32 a write speed of 17MB approx / sec and a read speed of 38MB / sec see picture gallery ... (!)
