Judging from his class was has a data transfer rate of up to 6 MB / s in theory yes it ( we can saw after use applications tested sdcard speed test) , and that's what my expectations when buying for Rp . 120,000.00 in one of the famous mall in Surabaya phone center , so my gadget that only 256 MB of internal memory can be much faster when starting applications while playing music ( multitasking) because some applications i put on the sdcard ( for that I use App 2 SD Free to be had in the Market or Play Store) .
