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.

My 1st HD in a computer was a whopping 20MB...

First HD upgrade I did cost $350 for a 324MB WesterDigital HD from I ruled...heheheh...

We're all old....

The first hard drive I remember was for the old UNIX system at my office. It was <1mb and looked like a wash machine where you had to load the platters from the top.

You win. :)

The smallest hard drive I remember is the one on our old 386 machine with DOS 4. It was 2MB and we upgraded it to 6MB. I think the machine had 256K of RAM. The whole machine cost over $3000.

The first hard drive I bought was for the first machine I built, a Celeron 333A machine. The hard drive cost $250 and was 2.4GB. Back then there was no reason for more space.

I think you remember wrong. When the 386 got released both ram and hard drives were bigger than that, typically around 1 MB ram and 20 MB HD.

My first computer was an 8086 with 640 KB memory, 5.25" drives only and 10 MB HD.

I know my 386 (SX) had a 14MB HD. It had no extended or expanded RAM, though. Nor did it have upper memory. 640KB, total. Isn't that amazing? Just 15 years ago, Windows could be run on 640KB of memory, and fit on a 14MB HD with plenty of space left over for games. If, as the article says, 2 TB can hold 17,000 fine jpeg images, then my 14MB HD could hold zero fine jpeg images - each image is about 118MB. One jpeg wouldn't fit on the average hard drive for several years.

Perhaps. I do know that we had the math coprocessor installed.

My first computer was a Coco from Radio Crap. It had 16KB of memory and a very unreliable tape drive. 1MB of hard disk would've been heaven to me at that time. There's nothing worse than saving a program that took an hour to write only to lose it even though you saved it 5 times to be sure... those were the days.

When I graduated to the 10MB on the 8088, I thought I was in *heaven*. I was too young for porn in those days. I remember copying games out of magazines (by hand). Those were the days... but to be honest, the BBS days were really cool. The Internet is great, and I'd never trade it in for those days, but I met a lot of flesh-and-blood geeks in those days.

First computer I owned was an Atari 800XL, 64K ram and I think single density 5.25" floppy at 640k storage. But it also had a cartridge slot for pluging in ROM cartridges just like the game console so my wordprocessor worked much faster than those who had to load them from cassettes or floppies. Those also had a co-processor for graphics which made it faster for video than other computers of the time.

Atari was in the way to making some great computers till the previous CEO's sons took over when he retired, they completely killed the company, he even came back two years later but was unable to do more than salvage some of the arcade game business they had.

So miss those days, when you had to actually learn something about computers to use them.

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 :)

My first Computer only had a 1.2MB 5.25" floppy. I bought a 30MB Hard drive for $300. That is MB not GB. Now I have 1.6TB on my HTPC.

Yeah, we are. Heh. The smallest drive I have laying around is a 130mb Toshiba 2.5" drive. It worked up until about 2 years ago when I accidentally dropped it. Doh!

Just think what our kids are going to say....

Man I remember when a cell phone was the size of a wallet...
Or I remember when they had these platter things called hard drives.... they only held terabytes of data.
I can't wait to hear the "I remember when's" about quantum computing begin

When I was a kid, son, pluto was a planet! I am 19, and the smallest old school drive I've used was 3GB, that I can remember.
