Memory Cards for Computers

Memory card readers are often provided on today's personal computers or are available as an optional extra, they may be internal or externally connected via fire-wire or USB.

Memory Cards for Computers: What is Backward Compatibility?
As products such as Computers improve their specifications from one generation to the next, there are compatibility issues to consider. Devices that only accept the original SD (Secure Digital) card format will not be compatible with SDHC (Secure Digital High Capacity) or SDXC (Secure Digital ‘Xtra Capacity’) memory cards. However, both SDHC and SDXC memory cards are backwards compatible, enabling them to read previous format cards. A device like a Computer is backwards compatible if products designed for the new standard can receive, read, view or play older or less powerful standards and formats.

  • SD devices can only use SD memory cards - SD capacities range from 128MB to 2GB
  • SDHC devices can use both SD memory cards and SDHC memory cards - SDHC capacities range from 4GB to 32GB
  • SDXC devices can use SD memory cards, SDHC memory cards and SDXC memory cards - SDXC capacities range from 64GB to 2TB
