[Q] Slow/Poor micro-sd performance
Hi, i bought some days ago an 8GB class 10 micro sd card, hoping it would speed up my phone (i was using app2sd+ with Kyrillo's ROM v7.1).
I didn't notice any diference compared to my old 4GB class 2 card, so i installed SD Tools app to test the speeds, and i realized all the cards i put in my phone get 4MB/s as the maximun write speed, i tried many different sd cards, class 2 and 10 and there's no difference. Then i tried the same cards in my girlfriend's Galaxy Ace and the speeds were much higher, 7~12 MB/s write speed.
I thought it was a rom problem, so i backed up with Titanium Backup and flashed a stock ROM (JPM), but the speeds remain the same (around 4 MB/s for writing), i also tried changing the buffer size from 128kb to 1024, 2048, 4096 with "SD Booster" and "SD Speed Increase" apps, but no good results...
Could my phone be faulty?
Is there any configuration i can try to make my sd card faster? any command line?
What are the speeds you reach with "SD Tools" and classes of your SD card?
