This article could go to many sections but I thought it would be relevant in this section. I presume this could be used in mobile phones :)

Transcend has launched industrial microSDHC cards in India, designed to deliver outstanding reliability for mission-critical applications.

The industrial microSDHC cards are built with high-quality MLC NAND Flash chips, are meant for non-stop applications that are often exposed to extreme operating environments.

Prices appear quite reasonable when u see the per GB cost! I got a 16GB card for my phone for 1200 odd, and this one costs only 900.

s if you check your card it should have the class number in a circle

like so.
Class Rating 2. Transfer speed is a minimum of 2MB/sec.
Class Rating 4. Transfer speed is a minimum of 4MB/sec.
Class Rating 6. Transfer speed is a minimum of 6MB/sec.
Class Rating 10. Transfer speed is a minimum of 10MB/sec.

I personally prefer Sandisk then Transcend in that order. I also see Samsung memory cards available on ebay nowadays

Class 10 cards have worse random access times than class 4 and 6. I wouldn't use them on phones. The speed is only write speed.

From xda-developers:
Class 2 and 4 cards have better random access speed and random read/write than class 6 or 10 cards in general. To get higher sequential write speeds, manufacturers sacrifice the random access speeds. That's just how it is.
The best all around card I've ever found is Sandisk class 4.
My 32gb Sandisk class 4 outperforms any other class 10 or 2 32gb card I've tested in the random access and random read/write speeds. That's what's most important when using with WP7 or Android when using it for apps or OS files that need to be accessed quickly. Class 6 and 10 cards are setup to initialize the area of the card that is about to be used to make the sequential write/read quicker, but it takes extra time in the beginning to do the initialization. If your using the card where you need to access small bits of info from various parts of card quickly, you will do best with class 2 or 4.
Most people seem to assume that the higher the class, the better the card is for everything, but that's not how it is. Different purposes need different kinds of speed... cards with higher sequential speeds have lower random speeds.
