These are still great memory cards despite being an older type of memory card compared to the SanDisk Ultra 64GB Ultra Micro SDXC UHS-I/Class 10 card with adapter which are much cheaper and faster per GB and more compact. However, some of us still need to use CompactFlash cards because of the devices we have. The CompactFlash card is an easy-to-use removable medium for transferring or permanently changing the content on a computer with a card reader. This 2GB card stores 36 hours and 25 minutes of MP3 audio at 128k or 1 hour and 33 minutes of WAV at 192k. Big difference! This could mean you have multiple audiobooks. They take up virtually no physical space and can go a long way in creating an audio library.
