SD Speed Increase
I am using 4 GB Kingston class 4 SD card on Android HTC HD2. Here is the result from SD Tools ~ Info and Benchmark tools. 10.5 MB/s for writing and 15.8 MB/s for reading on 2048 kb cache. Note – certain custom Android ROM already preset the cache value. So you don’t need to manually to edit it again.
