Kingston Technology's Secure Digital High-Capacity (SDHC) memory card is designed to meet the storage demands of high-quality digital still and video cameras and other high-resolution image recording devices.

With a 4 GB capacity, the SDHC card offers larger-volume data storage and optimized recording performance with support for FAT 32 file formats. With a Class 2 rating, the card delivers a minimum data transfer rate of 2 MB per second for optimum performance with SDHC devices.

For added reliability and durability, this solid-state SDHC memory card is built of nonvolatile memory components and has no moving parts that could wear out or break. Although identical in size to today's standard SD card, the new SDHC cards are designed differently and are only recognized by SDHC host devices. To ensure compatibility, look for the SDHC logo on cards and host devices such as cameras and camcorders. Fully compliant with the new Secure Digital Association 2.00 specification, this memory card is backed with a lifetime limited warranty.

Problem free. I use this in my Kingston MobileLite USB adapter and they work well with every computer I've plugged them in to. I also have Kingston 2GB SD, 2GB MicroSD, and 1Gb MicroSD, all have performed problem free.
