Speed / handling:
When using for burst shooting with 10 fps in RAW format (Nikon D3) I was able to record any difference to renowned CF cards. In my stash SanDisk and Lexar cards exist. These are from my practical use also not clearly perceptible faster! Perhaps there is in a measurement under specific conditions deviations (kämne on a test on) - but these results are irrelevant to the real practice of my user's perspective! I can not judge how the cards in current camera models such as Nikon D800 or Nikon D4 are currently working.
Robustness:
The cards were used in the summer on a desert tour in Egypt (Quad Race at +48 degrees Celsius with 6-8 frames / sec.) And three weeks ago in Kazakhstan at -22 degrees (3 frames / sec.). Even under these conditions from practical point of view no noticeable change in the Map Properties. Safe with increasing cold and required serial speed, the known impairments occur - from my experience even with identical renowned cards.
Conclusion:
Since I generally only review the handling and significant use of the card, I can "very good" give a date.
How did the card I can prove the long-term use still do not say - but will complement the recession in need. In my view, a clear recommendation in terms of price-Leistungsverhältltnis.
Supplement / long-term experience:
After using the card (Session shoots) is the first 32GB card after about 6 months use in my Nikon D3 failed error "CHA". On demand at Nikon this is due to the CF card. On the Mac and on the PC it is no longer recognized and can not even format! Unfortunately, here have been saved and only partially restore the NEF (RAW) files.
Warning: Anyone who needs reliability should approach with caution to the card!
On request guarantee at Komputerbay I got a 5-language-back information to England / Birmingham via mail! I'll send the card back and then me again Report with the result here again!
