iPhone 4S - I/O Performance ?
I'm curious about if I/O performance of iPhone 4S has enhanced or the same...
Could someone who has an iPhone 4S try to iBenchmark! and share the scores ?
iBenchmark! is free btw...
My scores for iPhone 4 w/ iOS [No JB] are here below:
Memory Allocation: 200.3 per sec.
Memory Copy: 863.1 per sec.
Disk Write: 20.5 MB/s
Disk Read: 101.2 MB/s

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...

Apparently write speed is 31MB/s to the flash memory - which is really superb.
Mem alloc again is great with the new A5 chip.
But honestly speaking mem copy ops puzzled me.
Though may i ask if those are the first run scores ? What happens after you run three times in row ?
