2TB max SDXC memory cards within reach

Posted by Scout on January 8, 2009

Running out of space in your memory card? Is the 32GB upper limit of the SDHC standard weighing you down?

My guess: Probably not, unless you’re into shooting HD videos. The standards-defining SD Association isn’t taking any chances, however, and is taking steps to make the SD format future-proof (for now, anyway).

They have just announced the creation of the SDXC specification (Secure Digital eXtended Capacity) which can provide up to a whopping 2 terabytes of storage capacity and accelerates SD interface read/write speeds anywhere from 104 MBps to 300 MBps. They will use Microsoft’s exFAT file system, also known as FAT64. Expect these SDXC cards to infiltrate the market later this year, starting with 64GB-128GB capacities, and working their way up to the published maximum within a few short years.
