A 4GB SD card increases the storage space of your phone, camera, laptop or tablet. While always useful, additional storage space is especially handy during holiday trips when you want to store a lot of photos and videos and bring your music with you.

SD cards come in three different formats: the standard size, micro, and the less frequent mini. You can purchase adaptors for larger sockets. The speed class of an SD card is important when recording videos. Lower speed classes, such as 4 or 6, can record in High-definition, but you need a class 10 card for Full HD experience. A 4GB SD card saves you the worry of running out of space and lets you capture all the precious moments.
