Thx rstark18 - i believe the scores you posted are very substantial.
I see mem alloc more than twice of iPhone 4 !
I don't know why your mem copy score is lower but i guess it's because some task in the background - although i didn't mention in my post i killed all task in the bg before executing the benchmark.
Disk write 30 MB/s is also spectacular too !
I've had similar tests with some friends Galaxy S II [GSM Europe] and Galaxy Tab [Original P 1000] and their writes are below 10 MB/s and reads are under 30 MB/s - of course for their internal storage. SD Cards are even are lower though maybe a Class 10 card may enhance the performance.
I don't think any other smartphone can beat iPhone 4/4S atm for the I/O performance.
IOS file system possibly effects this positively too...
