SDXC cards will be available in capacities up to 2TB

The Secure Digital (SD) format has come a long way since its original inception. Originally conceived as an offshoot of the Multimedia Card (MMC) format, SD cards have matured over the years into the Secure Digital High Capacity (SDHC) versions that are prevalent today for capacities greater than 2GB.

Current SDHC cards are artificially limited to just 32GB, which means that a new standard is being ushered in to boost capacities into the stratosphere. As a result, the new Secure Digital eXtended Capacity (SDXC) format was introduced today at CES. SDXC cards have a theoretical maximum capacity of 2TB and theoretical maximum read/write speeds of 300MB/sec.

The first SDXC cards will hit the market during the first quarter of 2009; however, these first generation cards will have a maximum transfer rate of 104 MB/sec.

"SDXC combines a higher capacity roadmap with faster transfer speeds as a means to exploit NAND flash memory technology as a compelling choice for portable memory storage and interoperability," said Gartner's Joseph Unsworth, research director, NAND Flash Semiconductors. "With industry support, SDXC presents manufacturers with the opportunity to kindle consumer demand for more advanced handset features and functionality in consumer electronics behind the ubiquitous SD interface."

"SDXC is a large-capacity card that can store more than 4,000 RAW images, which is the uncompressed mode professionals use, and 17,000 of the fine-mode most consumers use. That capacity, combined with the exFAT file system, increases movie recording time and reduces starting time to improve photo-capturing opportunities," said Canon General Manager Shigeto Kanda. "Improvements in interface speed allow further increases in continuous shooting speed and higher resolution movie recordings. As a memory card well suited to small-sized user-friendly digital cameras, the SDXC specification will help consumers realize the full potential of our cameras."

We should expect to first seeing SDXC cards from the usual suspects such as SanDisk, Lexar, and Kingston. SDXC will more than likely carry a hefty premium over current SDHC cards, but expect to see that price differential close with time.

...I later added an Amiga 500 (which rawked), but eventually gave in and bought a PC I think during my junior year in college. Swank 486SX at, I think, 33Mhz? Dialed into school with my external 2400 baud modem to get to the TSO screen to do my homework ;)

Ah yes, the A500. I had one of those with WB 1.3. I upgraded it to 1MB! with the trap door. I got sick of not having a battery backed up clock. Then I upgraded to a fat Agnus to get all chip mem. After that I installed an AdSpeed (14Mhz! 2X the original). Eventually even that got slow with 2 floppy drives, so I upraded to a GVP 68030 40Mhz side add-on with a 170MB SCSI HD and 1MB "Fast" RAM.

Those were the days when an OS fit onto 1 880KB disc and I actually knew what each file was for. Moria was the best game, although the interlace flicker on the images between levels was annoying. I never got around to getting a flicker fixer and multisync monitor. The Commodore (1084 I think was the model number) was hackable to run PAL at least for a bit more lines of res. It just required drilling out part of the rear casing to get to the other 2 knobs.
