A Kingston 8GB card may offer speeds that make a 2GB card from Connect 3D seem slow by comparison. If you're on a tight budget and don't have the need for speed, you should consider slower memory cards.

The Transcend 8GB SDHC - Class 6 has a fantastic reputation amongst those who want tremendous space and speed.

If your budget is a little lower and you'd like to best blend of space and speed for your money, consider Kingston's Ultimate SD card. It offers up to 2GB of space and has impressed critics with speeds that nearly match Sandisk's Extreme III line. Its comparatively-low price tag makes it a smart choice for the budget-conscious.
