ATP ProMax 4 GB SD High Capacity (SDHC) Memory Card Review
 

We had the opportunity to the take the 4GB ATP ProMax SDHC memory card for a test drive and our overall impressions are quite positive. Because the SDHC format isn’t backwards compatible with SD devices, you’ll need a special SDHC card reader if you hope to use this card with your computer. Thankfully, ATP has included one such reader for free as part of the package. What a deal!
