To those with HD camcorders that record to SD cards, prepare to rejoice. SanDisk has announced it is now shipping its new line of SD media cards, the Ultra SDXC, complete with 64 gigabytes of storage capacity. The new XC line of SD cards, which is said to be able to grow to 2 TB — yes, terabytes — of storage, boasts a 15 MB/sec throughput rate and can store up to 9 hours of HD video. SanDisk’s SDXC cards are based on the SD 3.0 specifications for maximum compatibility, and use the exFAT file system. Canon has already publicly said that all of its future VIXIA camcorders and PowerShot cameras will be compatible with the newer, more potent XC cards. We have SanDisk’s official press release queued up for you after the break.
