5. You own an MP3 player. One thing all MP3 player owners have in common: they listen to lots of music. If you're going to put your whole collection on cards, you're definitely going to need more than one. Plus, cards are a great way to make your own compilation of songs with a similar style or theme to keep for yourself or give to a friend.
THE 5 MOST COMMON MISTAKES PEOPLE MAKE WHEN BUYING FLASH CARDS.
How many pictures can I fit on a flash card?
It's only natural—we buy regular film based on the number of exposures it will hold, so we expect to purchase "digital film" the same way. Unfortunately, it's difficult to predict exactly how many photos you can fit on a flash card. That's because the file size for one photo depends on a number of different factors:
• Compression: Your camera might give you the option of choosing a compression format (such as JPEG or TIFF) or taking uncompressed photos. Uncompressed files are the largest, and compression formats vary in size.
• Colours: RGB photos (format for viewing on a monitor) are three times as big as black-and-white photos, and CMYK photos (format for printing) are four times as big as black-and-white.
• Your camera model and the shooting conditions: Each camera gives slightly different results, and you might even get a different number of photos per card depending on the subject you are shooting and the current light conditions.
Taking those factors into consideration, the following charts can give you some general guidelines for how many pictures average users can fit on various sizes of flash cards. By default, most digital cameras will use their highest possible resolution with best possible image quality. While this produces the best possible photos, it also means each image takes up more space on the flash memory card, decreasing the number of images you can save on your card.
• Compression: When you convert (also called ripping) your CDs to create MP3s, you can select the bit-rate level through the software you are using to convert the files. The greater the bit-rate, the larger the file size and the better the sound quality. A standard audio CD has a bit-rate over 1400kbps, which is why a CD can hold only a few songs. (At 1400kbps, a four minute song is 42MB.)
• Song Length: Simply put, the longer the song, the larger the file size. Taking those two factors into consideration, the following charts can give you some general guidelines for how many MP3s average users can fit on various sizes of flash cards. The actual number of MP3s per card can vary depending on the length of the songs, MP3 format, and player model.
Most of today's handheld computers or PDAs have a slot for flash memory. Extra flash cards give you room for more programs or large files. For instance, if you install additional applications on your PDA, such as games, an Internet browser, e-mail, word processing, spreadsheet, or your company's proprietary software, you'll probably quickly run out of storage space and will need an extra card. Also, if you store important data on your handheld, a flash card gives you an easy way to back up your data. Plus, many of the newer handhelds also double as MP3 players, audio recorders, and/or digital cameras. If you want to use these features, you'll almost certainly need more storage space to hold your photos and music. The size of the card you should buy for your PDA will depend on your reason for buying the card. If you're looking for extra storage space for your programs and files, we recommend buying the largest card(s) you can. If you want to use your card to back up data, you might be better off with several small cards so you can back up to a different card every day.
