[Q] OnePlus One 16GB storage I/O is slow topic

Hi all,

I have a OnePlus One CH version with 16GB. All Benchmark (for example AntTutu show storage I/O to slow for other devices) . Why, or is that normal? My friend have the same phone and there is no low score in storage I/O, he has 2560 point.
I have this score with stock/ak/boeffla kernel too.

"Tárolás I/O" means storage I/O.
