I have a PQI Micro SD card and I wanted more space so I just recently bought a second Micro SD card a SanDisk after loading it up I de-fragmented both cards and found that the SanDisk loaded faster. I decided to switch the files on the cards so that the stuff I use the most are on the faster SanDisk. I then found that my San Disk slowed down and my PQI speed up. Both cards are 2GB. I bought the MQI about two months ago and the SanDisk a few days ago. I want to know what makes some cards load faster then others even when the files are switched. Any ideas?
