Camera Memory Capacities - Table

The table below shows the capacity of different sizes of memory cards --- expressed as
  • number of photo files of various megapixel sizes (3, 4, 5, 6, 8, 10),
  • number of mp3 music files (4 minute songs recorded at 128kbps)
  • number of minutes of mpeg4 (or 3GP2 mobile phone format) low-res video files
    where low-res is less than 640x480 pixels :

NOTE1 (data accuracy disclaimer) :
Actual number of photos, songs, minutes will vary depending on camera/device model, format resolution, file compression, and usable capacity. Actual usable memory capacity may be somewhat less than the nominal memory size of the chip/card.

1 MB = 1 MegaByte is about 1 million bytes.
1 GB = 1 GigaByte is about 1 billion bytes.
1 byte is 8 bits (zeros or ones).


NOTE2 (data variability) :
The photo-count figures for 3, 5, and 8 megapixel cameras come from two different sources and indicate the variability of information that you may see in tables like these.

The figures in parentheses are from a Circuit City Sunday newpaper ad insert. The other figures are from an information card that came with a Lexar Platinum II SD memory card.

There seems to be too much discrepancy in the 5 megapixel data. This data may be compared with a 3rd source of information, then replaced or augmented.
