Since my 'old' SanDisk reader nor understood by SDHC SDXC something also had equal ran a new reader. My choice fell on the reviews here on Amazon to DIGISOL 47,201th
Test environment:
Windows 7 32-bit, Intel Q43 chipset
Software:
H2testw: Letter 16.7 MB / s read 18.8 MB / s
I am very pleased with these speeds. The reading speed might be slightly higher, but I can not judge whether because the reader is the bottleneck.
The card was at 25.11. bought on Amazon. Variations from batch to batch are known to be not uncommon.
And to everyone who wrote that no class is 10:
The writing speed of Class 10 is specified at least 80 Mbit / s (10 MB / s).
Who this is not achieved with this card, which has
a) an old chipset
b) a slow read / write unit
c) the wrong tools to measure this.
or
d) a defective card, which unfortunately can happen.
It would be desirable a plastic sleeve. At a retail packaging, I would expect something like this before. Not at a bulk version.
Who has the permanent card in the camera, but this will not interfere with the next - so I prefer for it not also half a point from.
Edit:
After half a year of continuous use in a Panasonic TM-707 Full-HD camcorder, the map still works perfectly.
Since so many problems with their Canon SLRs that may suggests that there are series of series big differences. None of these people but let a benchmark run across the map. Therefore, it may also be that the memory management of the Canon just plain bad (to lower the latch and / or the processor used is just too slow). The Panasonic has the processor after all, with a fan cool :-(
