Addendum: speed test
Today I have the Transcend SDHC 32GB, Class 10, 600x, UHS-1 card bought and chased through the ATTO benchmark.
For this I use the Lexar USB 3.0 Dual Card Slot Reader to USB 3.0
When I run the map directly in SD slot of the reader, she goes off right.
If I now operate in the CF adapter and test them in the reader (of course, then the CF slot), they lost quite a performance.
Add to that a comparison value my previous real CF Card: Sandisk Ultra II 4GB
Direct SD slot in the reader: 68.044 MB (Write) / 95.698 MB (Read)
About CF adapter in Reader: 23.967 MB (Write) / 25,500 MB (Read)
CF Sandisk Ultra II: 9.956 MB (Write) / 12.561 MB (Read)
Conclusion: (why only 3 stars)
- The adapter supports SD (HC) card for my Canon EOS400D
- The speed of fast SDHC card in the adapter is about twice as fast as in my previous CF card (However, there are even faster CF cards)
- In the CF adapter has a fast UHS card by no means the rate that they could actually deliver.
- From the CF adapter out directly in an SD slot, you have a very fast read speed and is therefore only in the Camera of the write operation of the bottleneck
Vorrausgesetzt, one uses a fast USB 3.0 reader and a fast SD card (there is also sky-wide differences).
- Unfortunately, I can not measure whether my camera in write mode to the SD card via the CF adapter is even slower.
Nevertheless, the adapter is recommended. Maybe we so its speed in an update that further drilled.
ADDENDUM II: ------------------------------------
Now that I have tested the adapter with different SDS, I can say conclusively that the CF adapter in itself
Both read and write at a maximum of 25 MB / s levels off (if permitted by the card). More is not in it.
