But now the most important:
Since the reviews turn out very differently here I have subjected this card immediately a test.
I must honestly confess I was taken aback when I saw the first measurement: The map is but actually faster than indicated. First test file corresponded to 256 MB and had a write rate of 42 MB / s and a read rate of 76 MB / s.
So I made a test again, this time with a 2 GB Full HD video, this test is also available as Amazon image available.
The following values were determined: 52.6 MB / s and 81.3 MB / s read.
These are values that I know of 95Mbps to date only from my SanDisk Extreme Pro.
Has been tested on the hardware with: Macbook Pro 13 "2011 with 8 GB RAM with built-in high-speed card reader It is absolutely reliable values..
I can really recommend this SDXC 64GB.
And of course it is also 50p and even Ultra HD suitable partly recordings with these performance data for all kinds of Full HD.
I myself use this card in my Sony Full HD camcorder, but also from time to time in one of my 3 DSLR cameras. Up to now, without any problems.
Therefore, full 5 stars.
