Kingston 32 GB microSD Class 10 Card Review

Testing in the Motorola Droid 1 (Android Second Gen Hardware)

We used two apps freely available in the Android Market to test the speed of the microSD card.

• SD Tools
• Jdisk Bench 3.0

SD Tools

This app was used with its default settings to test the card.

JdiskBench 3.0

This benchmark can be used to test the read and write speeds of the SD card with different unit data sizes. Our testing included writing 50MB of data in 4KB and 1024KB unit sizes and then reading it back. However, we also used the Android cache size trick to vary the cache size to see the effect it had on the transfer speeds.

We do not see difference between the cards in most of tests. In most of the tests, the class 10 card lags behind the class 2 card. Only in the last test – when reading data in 1024KB unit size with the Android cache set at 4096KB – that we see for the class 10 card beating the class 2 card handsomely. One of the reasons that both the cards end up performing similarly, could be due to being limited by the older generation SOC being used in the Motorola Droid 1. To see if newer hardware would make a difference, we also tested in a Samsung Galaxy S Fascinate. Let’s take a look at those results on the next page.
