If massive storage and speedy data rates are your thing, then your best bet for miniSD cards are the new high capacity miniSDHC (SD High Capacity) cards from Kingston (your phone does support SDHC formats, right?). While there are plenty of other options for high-capacity external storage media, Kingston’s range-topping Class 6 miniSDHC cards are the cat’s meow when it comes to sustained data transfer rates. The 4GB miniSDHC Class 6 memory card zooms along at a minimum transfer rate of 6MB/s, making it “king” of all miniSDHC cards.
The Class 6 model is complemented by two lesser models in the product lineup – the Class 4 and Class 2 iterations of the 4GB miniSDHC card. But, with the Class 2 cards priced at $62 and Class 4 cards commanding $64, we’d be willing to shell out the couple extra bucks (literally) for the speed-king Class 6 card ($66).
