SD Association announces SDXC standard

Will SD cards be able to rival hard drives for storage capacity anytime soon? Probably not, but it won't be because of a technical limitation the next generation of SD cards, dubbed SDXC, have been announced this week. Among other things, the new format for the cards will result in a theoretical size limit of a massive 2TB, 64 times greater than the current 32GB limitation. That's a significant jump, considering that 32GB SDHC cards have been available for only about a year.

The SD association has been working to retain the existing form factor and interface for SD cards, but is pushing the technology forward at a very rapid rate. The SDXC standard will supposedly provide cards that will start at read/write speeds greater than 100MB/sec, and in the future could go as high as 300MB/sec. SD is a very popular format, particularly for devices like digital camcorders and cameras. With HD cameras becoming more popular and the amount of space needed to store high quality video increasing rapidly, SDXC is trying to keep up and fill that need.

OK . . . I'll gladly be the first to go on record predicting this is going to be "VAPORWARE" (you'll never see this anytime in the near future). I refuse to believe they're going to have a 2TB SD card . . . no way, no how!

by the time we have TB SD cards, SSD's better be damn cheap

And how is increasing the speed and capacity of an interface "vaporware"? Is SATA-II vaporware just because no HD can actually achieve 3.0 Gbps transfer rates? Was the ATA-6 standard vaporware because no drive even approached 2TB years ago?Just because SDXC supports up to 2TB capacities doesn't mean there will be cards maxing it out immediately. If that were the case, the standard would be obsolete before it was released.SDXC will be a great boost to the SD line. It will guarantee its continued success for years to come.

Its a good idea... given theres some 64gb SD cards out that aren't exactly bound to a standard yet. The limit is really high but its a good idea that means the standard won't keep getting changed every 4 years now.
