Despite the class 4/6 rating, the speed actual varies...

I have a kingston 8GB SDHC Class 4 card comes as a free gift...

Today I bought a Sandisk Ultra 30MB/s Class 6 16GB card..

Although the sandisk has a higher rating, but in my camera 550D give one burst 6 raws... the Class 6 writes the raws in 20 seconds while the Class 4 Kingston only need 15 seconds..

Put in card reader and it shows that the Sandisk has a higher read 17MB/s compare to Kingston's 14MB/s
But with a lower write performance: Sandisk 6.6MB/s versus Kingston 6.9 MB/s

All read/write test has been performed 3 times to average...

The Kingston although is a Class 4 card, but actually has a Class 6 performance.. The Sandisk, however, just met its Class 6 but not more..
The claimed 30MB/s from Sandisk don't know how to reach....

At least they met the specs and this could only be just this piece. Won't bet everyone would be the same. :)
