SDXC memory cards

SDXC memory cardSDXC (eXtended Capacity) memory cards store data more than 32 GB and up to two terabytes and have read/write speeds to 104MB per second. According to the SD Association, some SDXC cards will be able to store more than 17,000 photos, 4,000 RAW images, 100 High Definition videos, or 60 hours of HD recording.

This new technology will eventually offer speeds up to 300 MB per second and can be used in SDXC-compatible consumer electronic devices such as digital and video cameras and mobile phones.

Only use SDXC Memory Cards in SDXC host products

It’s important to note that SDXC cards should not be used in non-compatible host products. According to the SD Association:

  • SDXC memory cards can be used only with SDXC host products.
  • SDXC host products can use SD, SDHC and SDXC memory cards.
  • SDHC memory cards can be used with SDHC and SDXC host products.
  • SDHC host products can use both SD and SDHC memory cards.

SDXC host productsThe association also offers this warning:

“If an SDXC memory card is inserted into a PC or a host product that does not support SDXC memory cards, a message may prompt you to format the card. Do not format the SDXC memory card in a non-compatible host product; it will erase the data on the SDXC memory card and format the card for a different file system that will no longer work with SDXC host products.”
