Transcend Ultimate SDHC Class 10 Card (8GB, 16GB)
Transcend sent us two SDHC Class 10 cards, a 16GB and an 8GB model. The specification section on Transcend's site specs these cards at 10,000 insert/eject cycles and operational temperatures between -25°C to 85°C. The card should be available for less than $100, and Transcend provides a 30-year warranty.
We found the 8GB model's throughput slightly lower than the 16GB version, but the difference is too small to consider when purchasing. Access time is almost the same for both cards (1.2 to 1.3 ms), and the difference in throughput might only be noticeable if you need to write large amounts of data onto the cards within a short time.
The 8GB card is faster when it comes to I/O operations, but both cards don’t deliver sufficient IOPS to host an operating system.
