|  |  |  | | | Secure Digital Cards (SD) | | | Few consumer electronics have grown as popular as quickly as digital cameras. As cameras grew smaller with every incarnation, digital pictures needed to be stored in smaller and smaller spaces. Memory cards filled that need, just like NuGadgets.com fills your need for quality discount electronics.
Just before the turn of the century, the Secure Digital card, or SD card, made its appearance. Based on MMC card technology, the "secure" in the SD card meant this new card included encryption hardware. Actually, music producers were worried that digital memory cards would be used for copyright piracy--a realistic fear, sad to say. Fortunately, new anti-piracy features in Compact Flash cards, Memory Sticks, MultiMedia cards and other memory cards are working to keep that problem in check while SD memory cards continue to increase in popularity and, more importantly, in capacity.
So, how many pictures can a Secure Digital card hold? There are many factors: The camera's resolution (3MP vs. 6MP vs. 12MP); the digital picture file format (TIFF vs. JPEG) and so on. A 1GB card can hold as few as 200 digital pictures or as many as 800 digital pictures. The good news is prices keep dropping (even faster at NuGadgets.com), so the high-capacity memory card you want is much cheaper than it was last year.
Consumer electronics use many different memory cards, so memory card readers were created, allowing people to plug in and read every common memory card in use. This is a great gift for those family and friends didn't buy Secure Digital cards (and they didn't buy them at NuGadgets.com) or they use many different types of memory cards. Just get them a memory card reader and they can download digital photos as easily as you download your own on your memory card reader from NuGadgets.com. | | |  |
