TTDSi takes long time to load roms

My TTDSi takes a long time to load roms,ever since i got it, up to 2 mins but usually around 60-70 secs. I have ran the tti check and the cart is real. i have tried using YSmenu but the load times are the same. i also used an inofficial infolib.dat update file from http://sites.google.com/site/weeklyinfolib/Home that is supposed to speed up loading times. There is still not much of a difference. I have reformatted with FAT and FAT32. No dif. Also, i have updated the official ttdsi firmware to 1.17a12, to no avail. btw, i am using a 4gb kingston sdhc. Can anyone help?

I have the same problem with kingston microcards so I only use Sandisk now, and they work fine.

Thanks, I'll try it.
