Test winner in the Color Photo 7/2012, but not with me!

The biggest annoyance with my Sony SLT-A77 camera is the fast continuous shooting (12 frames / sec) in my opinion for sufficient internal frame memory (13 images at 24 megapixel RAW + JPEG). From the 14th burst can cause an image again when enough data has been written in the internal frame memory to the SD card. This results in a series of shots to (usually) uncomfortable pauses, dependent on their length directly from the write speed of the data on the SD card. So I looked for an SD card with maximum write rate. Through a review ("27 SDHC memory cards and XC") in the Color Photo 7/2012 I opted for a 32GB Lexar Professional UHS I, 600x (90MB / s), based on my positive experience with SanDisk products, I also ordered SanDisk 32GB Extreme Pro still a UHS-I (95MB / s), which in addition also was still a bit cheaper than the Lexar card (64.80 versus 69.64). Amazon typically, met both cards the very next morning at me - SUPER! Along with some other SDHC card which I already own some time, both newcomers had then same time for a comparison test to serve (camera settings (Sony SLT-A77): Picture quality: 24 Megapixel RAW + JPEG, Focus: manually (so camera no time prior to triggering for focusing spending), continuous shooting: Hi, recording mode: "M" (manual) at f = 4.0, s = 1 / 1500sec, ISO 200, Auto White Balance):

A method of measurement: stop time required for the camera to make 13 + 10 shooting. So: press release button and simultaneously start stopwatch.. The camera starts to make to fast continuous shooting. After a short time (13 pictures) is the internal image memory is full u. The interval between shots will dramatically greater. Yet right now 10 pictures make u. Then stop time.

Results A (for 23 continuous shooting):
1) SanDisk SDHC 32GB Extreme Pro UHS-I, Class 10 (95MB / s): Time = 9 sec.
2.) Lexar SDHC 32GB 600x Professional UHS-I, Class 10 (90MB / s): time = 10 sec.
3.) SanDisk SDHC 32GB Extreme HD Video, Class 10 (30MB / s): time = 15 sec.
4.) PNY SDHC, 32GB, Professional, Class 10 (20MB / s): time = 23 sec.
5.) Toshiba, Micro SDHC, 32GB, Class 4: time = 63 sec.

Measurement Method B: As A measuring method, however, stop the time until the camera has all the images stored completely on the SD card (ie until the red LED turns off write). So: Once all the pictures were taken, release the shutter button and watch the red glowing write-LED (located on the right rear control dial below).. Time stop until this LED goes out.

Results B:
Regardless of the inserted SD card always 23 images were triggered, had to be written to data on the card to their storage 630MB.
1) SanDisk SDHC 32GB Extreme Pro UHS-I, Class 10 (95MB / s): time = 17 sec.
2.) Lexar SDHC 32GB 600x Professional UHS-I, Class 10 (90MB / s): time = 22 sec.
3.) SanDisk SDHC 32GB Extreme HD Video, Class 10 (30MB / s): time = 32 sec.
4.) PNY SDHC, 32GB, Professional, Class 10 (20MB / s): time = 51 sec.
5.) Toshiba, Micro SDHC, 32GB, Class 4: time = 145 sec.

Conclusion: The SanDisk SDHC 32GB Extreme Pro UHS-I, Class 10 (95MB / s) is my "fastest horse in the stable" and therefore gets full marks.. Although the Lexar's Award winner in the mentioned comparison test from the Color photo (which was also made with a Sony SLT-A77), but with me it falls in both tests behind the SanDisk Extreme Pro. While moving the differences in the range of seconds, but if you are not photographed still lifes, this can be critical (I speak as u from bitter experience. Set since only the fastest SD card). Since it is slower and more expensive compared to the SanDisk Extreme Pro, gets the Lexar 600x Prfessional of me "only" 4 stars.
