Imagine putting all 2,000 of your favorite MP3 songs into a memory card no larger than your fingernail. A few years ago that would have been a tall order, particularly since the CompactFlash media was the only one with storage capacities above 4GB. But today, with the launch of SanDisk's 8GB microSDHC and M2 (aka Memory Stick Micro) cards, it's no longer an impossible task.
Widely considered as two of the world's smallest flash memory formats available today, microSD and M2 cards are most commonly used in handheld devices such as mobile and smartphones. The availability of card adapters, which convert the microSD or M2 cards into other larger flash memory formats (such as Memory Stick Duo and SD card), has also enabled the tiny cards to be used more widely in other devices as well.
According to SanDisk's press release, the 8GB M2 card is now available in stores for $130.99, while the 8GB microSDHC media is priced slightly more competitively at $118.42. But before you invest in the latest 8GB microSDHC and M2 cards, do note that not all devices will work with them. The microSDHC card, for instance, will work only in devices that support the SDHC (Secure Digital High Capacity) format. The M2 card, on the other hand, is expected to work with all devices, but we'd advise checking with your device manufacturer to ensure compatibility.
