Fast, fast, fast!

This review is from: Transcend 16GB SDHC Class 10 Flash Memory Card Up to 30MB/s (TS16GSDHC10) (Personal Computers)
I bought this card for my Canon T1i. The card I had been using before ordering this one was a Kingston Class 6 micro sd card and it worked well enough for the type of shooting I did. Class 6 was the card speed that Canon recommended when I bought my T1i (Class 10 cards were not yet available) and it seemed fast enough for the way I used my camera - isolated single photos taken at Medium (8 MP) or Large (15 MP) jpg settings and 1280 x 720 video. And while I ocassionally took continuous photos, I had never much exceeded 5-10 photos in a row and had never run into a problem with my Class 6 card.
When I first saw the Class 10 cards I did some experiments with my camera. How many continuous Large photos could I take before the camera slowed down? It turned out to be about 30. And how many RAW photos could I take before the camera slowed down? It turned out to be about 9. SInce I did not generally take any photos in RAW and never needed more than about 10 continuous photos at Large, the Class 6 card seemed more than sufficient for my needs. But I wondered about the speed of the Class 10 cards enough that I finally bought one.
It turns out that the Class 10 card is sufficiently fast that there does not seem to be a reasonable upper limit on single Large photos. I have taken 60 on continuous without an issue. And although I still cannot take more than 9 RAW photos on continuous with the Class 10 card, when I am finished taking those photos the camera no longer displays a Wait - writing pictures screen. The RAW photos get written from the built-in memory to the card so quickly that the camera does not need to display the Wait screen.
So this card is fast! Given the way I take photos this purchase was unnecessary, but still I am glad I bought it. I know I will not run into a situation where speed is an issue with this card.
