[TIP] Speed Up your SD CARD

[SCRIPT] FOR CLOCKWORKMOD RECOVERY ONLY

Many of us are disapponted with the kind of sd card they have it doesnt matters whether you have a class 10 or class 4 sd card the reading speed of sd card is very slow

however the same sd card works fast in your PC RIGHT ???

Actually it Depends on the Cache size for reading of the SD CARD

CHECK YOURS
/sys/devices/virtual/bdi/179:0/read_ahead_kb
It is Set to be as low as 128kb and in some roms its Only 4kb

But Here is where The members of XDA come to save you

XDA MEMBER : BRAINMASTER has made a script to Increase the Cache Size of the SD Card

Find the Best size which suits your SD card But our Recomendation is that you flash the 2048 kb file that works best on all SD Cards

FLASH THE SCRIPT THROUGH CLOCKWORKMOD RECOVERY

DONT FORGET TO COMMENT WHETHER THIS WORKED FOR YOU OR NOT

Downloads
128kb Default
1024 Kb
2048Kb
3072Kb BEST FOR MOST OF THE CARDs
4096Kb Ultra Fast

it works!!
before flashing this patch, my SD just 2.3 Mb/s (W) - 12 Mb/s (R), after, 2.5 Mb/s (W) - 25 Mb/s (R) (3072Kb patch)

fyi, the 4096Kb patch don't give me more performance than the 3072Kb, it's only give me 2.3 Mb/s (W) and 24 Mb/s (R)
