There are various formats for memory cards. SD memory cards can have capacities up to 2 GB. I use them in my computers, portable digital assistants, cameras, and telephones.
I knew the day would come when I would need to seriously consider “the next format”…that day always comes. I have a tablet PC that would not read 1 GB SD cards…until I updated the BIOS. When necessary, I had been using USB card readers to access memory cards (that my computers would not).
The SD High-Capacity (SDHC) cards go up to 32GB, and:
“SDHC-enabled products accommodate SDHC memory cards and are backward compatible with SD memory cards. Data on SDHC cards is protected even if inserted in an incompatible device. SDHC cards also work in standard SD slots with a firmware upgrade.”
Beyond SDHC, SDXC (eXtended Capacity) memory cards are coming: up to 2 terabytes (TB) of storage per card…that could be 100 HD movies per card.
