Test results: File system
To measure how fast the phone can read from and write to the internal memory, we used the Antutu benchmark that indicates both speeds in megabytes per second.
The benchmarks show that the Galaxy S3 reads better than it can write. Despite numerous repetions of the test the write speed remained below 15 MB/s, which is considerably slower than HTC's latest phones. The read speed of 35 MB/s is very fast, on the other hand.
