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.

Pffft you had it MADE !

My first "computer" was a Tandy T100 ( yes, someone called Tandy actually made computers ). It had uhhh NO Ram, no HD, and you hooked it up to a TV because monitors didn't really exist yet for home users.

I'm pretty sure it had Ram. Anything Rom-only based would be totally nonprogrammable.

My first PC, an "Elf", had a grand total of 256 bytes (not MB or even KB) of Ram, and a couple 7-segment LEDs for a display. Monitor or even TV output? Don't even think about it.

Now come on the T100 had RAM -- 8KB on the first ones & later a massive 24KB ... OS overhead was 3130 bytes, Included were prductivity programs & a BASIC interpreter in ROM.

Although it was a private labeled Kyocera sold by Tandy not an actual Radio Shack design like the TRS-80 series.

Info from:

I started with the TS1000 (Timex licensed Sinclair ZX81) 2KB RAM for programs, display & OS overhead. Though it could be expanded to 16KB and there was a 64KB memory card that used banking to access the extra 48KB :)
