5.0 out of 5 stars A fast card makes a difference for the right camera, August 9, 2009

Length:: 1:12 Mins

UPDATE: May 13, 2010
I was contacted by an Amazon shopper named Rolla Gravett. He purchased a Transcend class 6 card that could maintain the 4.5fps to 100 shots. It could be a fluke but in the interest of relaying the facts, I'm letting you know that he offered video as evidence of this feat. Neither my Transcend class 6 card or class 10 card will do this.

Please let me know if anyone else has had this observation.

To respond to a request, I've changed the video today and included the test shooting in Raw mode. As you can see I'm not getting the 4.5FPS that I got in fine mode. This was about the same time that I shot 100 images in fine mode. Thank you for your suggestion. I got 56 images in just under 24 seconds. On my Transcendclass 6 card I got 25 shots in the same mode/time. My Transcend Class 10 card captured 37 images. In my opinion this is a much better demonstration of the card's write speed.



I have an Nikon D90. I purchased the 8G San Disc Extreme III card 30MB/S and a Transcend 16G class 6 card at the same time. The San Disc Extreme 3 card is incredibly fast. I get 100 pictures (4.5 frames per second) at fine resolution before the camera slows to buffer in 24 seconds. The Transcend card gets 17 photos on the same settings then pauses to buffer and only delivers 25 shots in 24 seconds. The Transcend Class 10 card delivers 66 shots in 24 seconds.

If you have the camera that can take full advantage of this write speed, this fast card is worth the investment. No more cringing while I wait for my camera to clear its buffer so I can take more pictures.

I like to shoot at 4.5 frames. It gives me a lot to pick through when I edit, but a lot can happen in a fraction of a second that can make a photo good or bad. Having the capability to hold down the shutter release and rattle off large bursts of photos is important to me.

I know this test is boring but it is a real world use test. I don't work for San Disc and would consider any other card with this write speed. A word of caution, all class 10 cards are not rated at 30MB/s, they only need to read and write at 10MB/s to be called class 10.

I have found that 8G is a good size for SLR Photography. In my opinion bigger cards are putting a lot of eggs in one basket.

If you have any questions or criticism please comment. I'll redo/repost the test if you can think of a way to make it better.

5.0 out of 5 stars Time tests on this card, July 13, 2010

Some time ago I purchased a Transcend 16 GB Class 10 card and reviewed it as "Fast, Fast, Fast". Later reviewers pointed to the printed speed on the actual cards (and on the corporate web pages) (Transcend - 20 MB/sec, Sandisk Extreme - 30 MB/sec) as an indication that the Transcend card was not particularly fast. Since the term "speed" itself is pretty much a subjective description, and since the speed of the card also depends upon the speed of the camera hardware and software, I thought it might be worth speed timing the different cards in my camera (a Canon T1i).

My original card, before I bought the Transcend 16 GB Class 10, was a Transcend 8 GB Class 6 (actually a micro-sdhc card) and my review of the Transcend Class 10 card was based on comparison with that card. I bought the Sandisk Extreme card (8 GB since it was pretty expensive) and tested each.

The actual timing tests were simple enough. I formatted each card before each test. I then took 20 continuous photos at 8 MP, at 15 MP and at RAW, and recorded the time from the start of taking pictures to the time when the recording light turned off.

Timing:

1) Transcend 8 GB, class 6

Format - 51.5 seconds,

20 continuous photos, 8 MP, least compression - 8.6 seconds,
20 continuous photos, 15 MP, least compression - 13.4 seconds,
20 continuous RAW photos - 44.3 seconds

2) Transcend 16 GB, class 10

Format - 46.2 seconds (the other cards are 8 GB so this time is not relevant. I included it for the sake of completeness),

20 continuous photos, 8 MP, least compression - 8.4 seconds,
20 continuous photos, 15 MP, least compression - 10.8 seconds,
20 continuous RAW photos - 31.4 seconds

3) Sandisk Extreme 8 GB, class 10

Format - 8 seconds,

20 continuous photos, 8 MP, least compression - 8.0 seconds,
20 continuous photos, 15 MP, least compression - 9.7 seconds,
20 continuous RAW photos - 27.4 seconds


Results:

1) Clearly the Sandisk Extreme formats much faster than the Transcend Class 6. A comparison with the 16 GB Transcend Class 10 card would be invalid since the sizes are not the same and there is no evidence that timing for formatting is linear. That is, there is no reason to believe that it would take twice as long to format a 16 GB card as an 8 GB card. It might take more, it might take less,

2) Taking photos at 8 MP, least compression, is nearly the same for all cards. Canon recommends a Class 6 card for the T1i and it appears that that is sufficient for photos taken at 8 MP,

3) Taking photos at 15 MP, least compression, showed a significant difference depending on the card. The Transcend Class 10 card took almost 20% less time than the Transcend Class 6 card and the Sandisk Class 10 card took about 10% less time than the Transcend Class 10 card,

4) Taking RAW photos also showed a significant difference depending on the card. The Transcend Class 10 card took about 29% less time than the Transcend Class 6 card and the Sandisk Class 10 card took almost 13% less time than the Transcend Class 10 card.

Conclusions:

Some things seem clear to me.

1) The Transcend Class 10 card was clearly faster in all categories (except 8 MP) than the Transcend Class 6 and that was the basis for my review of the card. In my opinion the upgrade from the Transcend Class 6 to the Transcend Class 10 was worth doing given the way I take photos (15 MP, ocassionally RAW).

2) The Sandisk Extreme Class 10 card is faster than the Transcend Class 10 card when used in the camera to take pictures larger than 8 MP (the difference at 8 MP is 5% which is not, in my opinion, significant). Clearly the difference between the Transcend Class 10 and the Sandisk Class 10 is significant although the user would have to determine if the 10% and 13% differences were worth the difference in price (the Sandisk 8 GB Class 10 is more expensive than the Transcend 16 GB Class 10). Given the way I use my camera I feel it is not worth the difference in price, but others may feel differently.

3) The difference in speeds between the Transcend Class 10 and the Sandisk Extreme Class 10, when used in the camera, are very different than the theoretical differences given the posted speeds. Given those posted speeds, a user might well expect that the Sandisk Extreme would be about 30-35% faster, but it is not and one has to assume that the difference is caused by the speed of the camera hardware and software.

I rated this card as 5 stars although the extra speed was not significant enough for me to justify the extra cost. Still, the card is faster than my Transcend Class 10.

Works very well with my Canon Rebel T1i. Very fast and I don't get buffer bars when recording HD videos. This is a Class 10 SDHC and it really is worth every penny you pay for it. Frustration-free packaging is a BIG plus!
