Burst Mode Test

The high write speeds could certainly be felt in our 30-shot burst test with an SLR camera. In fact, the same shooting frequency was maintained for all 30 photos! In practice, then, this card could keep up with our test camera's maximum burst rate of three frames per second with no loss in shooting speed.

Storage solutions manufacturer Transcend has also brought out a range of SDHC Ultimate Class 10 memory cards, available in 4, 8 or 16 GB capacities. The manufacturer claims that its ground-breaking new card can achieve read speeds of up to 20 MB/s and write speeds of up to 16 MB/s. Needless to say that with spec like this, we were expecting this Transcend SDHC card to pack a serious punch.

Neck and neck with the Sandisk SDHC Extreme

This memory card performed very well in our tests, with a read speed reaching up to 18.9 MB/s when faced with our barrage of files. It's therefore hot on the heels of the Sandisk SDHC Extreme 16 GB with its read speed of 19.4 MB/s under the same conditions. The Sandisk card still clearly leads on write speeds though, with 18.2 MB/s compared with 17.6 MB/s for the Transcend card.
