Pretec shows off 32GB SDXC card at PMA |
For a long time now digital cameras, phones and other devices have relied on SD cards for storage. The capacity of normal SD cards topped out at about 4GB and opened the door for SDHC cards with much more storage capacity. The SDHC card is now hitting its capacity limit opening the door for SDXC cards of the future.
The SDXC card can put as much as 2TB of storage inside a tiny card that looks like a SDHC card. The two formats are not compatible because SDXC uses exFAT file system compared to SDHC’s FAT32 file system. Pretec is showing off the first SDXC card at PMA in Vegas this week. The card has 32GB of storage space and has a read/write speed of 50MB/s. In the future read/write speeds will be as high as 300MB/s.
The biggest catch with the SDXC format today is that there are currently no devices on the market that use the format. This is a clear case of the old chicken or egg dilemma. Manufacturers won’t offer cameras that use the format until memory cards are available. Now that at least one card is on the market, perhaps we will see cameras and other products that support SDXC hit the market.

The SDXC specification was released to members on April 14, 2009. There are no legitimate SDXC memory cards or host products on the market prior to this date.
SDXC memory cards are for capacities above 32 gigabytes; therefore the first SDXC memory cards will offer 64 gigabyte of storage.
The Association expects a variety of companies to claim SDXC capability. To help ensure you are purchasing legitimate products meeting SD interoperability and performance standards, we recommend that you confirm any company’s claims by verifying membership in the SD Association by visiting: http://www.sdcard.org/developers/about/member_companies/
