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.

2Tb on an SD stick...

*smacks self in head*

2Tb on a wafer thin SD card.

I remember seing one of the very first 1Gb hard drives to make it into production. It was externally housed in a case nearly as big as a mid-tower ATX PC. And probably cost like $3,000.

Damn, I'm old. When did I become old? And why wasn't I notified?

Now if you'll excuse me, I'm going to go gum my breakfast mash.

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.

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.

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 :)

Looking at NewEgg, I don't see any over 4GB. I think you can get 8GB, but we won't see 2TB cards for awhile :)

The thing is, the current specification, SDHC, has a theoretical max capacity of 2TB, but they limited it artificially (as the article noted). So this really isn't news, they just removed the artificial limit, and manufactures are now "allowed" to make bigger cards.

There's no tech breakthrough or anything as far as I can tell. Not that I don't enjoy the idea of a 2TB SD card :)

32GB have been available for a while, for example here:

It was quite silly to limit SDHC to 32GB, that's only 16x capacity of a standard 2GB SD format. SDXC offers 64x capacity jump, so it's a bit better.

Agreed, this just looks like a "standard" being announced. How physically big would a card be today, that was 2TB? A Terabyte is at least 2 orders of magnitude larger than most SD cards or on the market. (neweggs largest today is 6GB) but flash drives are bigger, up to 64GB so far I think. I use flash drives more than the cards themselves.
It will be more than a few years to see anything close to a terabyte in a SD card.

Thye're all about the same for $/GB: cheap! 32GB at $128 gets more expensive.

Why is it at least 6x the cost per gb? Why are we not all just throwing a bunch of SDHC cards together and running our computers on them? Why does the x-25m need all that extra hardware?

Well the write/read speeds are one. A good portion of cheap sdhc cards cant even write over 20 MB/s. The Intel drive can do something like 170. Normal hard drives can do between 70 and 100.

I also know it needs extra hardware to manage that data. Once instance that comes to mind is that flash can only be written a certain number of times before it wears out. This is ok for flash cards but hard drives can make small changes 100s of times. This drive would wear out in no time so it manages the writes in such a way that writes data evenly to make it last longer.

Its pretty new tech anyway which has considerable Research and Dev costs so they need to be sold for a premium to make back some of those costs.

It is true Windows won't let you format a large hard drive in FAT32. However, you can use 3rd party software to format any size hard drive in FAT32. I have seen a 500GB hard drive formatted this way as a single partition and it works fine. Problem is FAT32 can't handle extreme large files such as 6gigs.

This article only states that a new specification is available that will extend ultimate capacity towards 2Tb. Doesn't mean that someone has a 2Tb stick to sell you.

Similar to 40bit PAE, where something like 5peta-bytes are addressable, doesn't mean anything has been made that can take advantage of it. Current SDHC cards are theoretically limited to 32GB, but I don't believe any are offered at that size.

My first rotating magnetic memory device was the size of a small washing machine and held only 5 MB. It was a huge jump several years later for a 300 MB drive that fit into a 19" rack (6U height). (The stupid head of IT bought a bare bones drive and it fell upon me to write the drivers *and* build the enclosure and physical interface too!)

My first solid state drive was a special one of a kind back in the early 70s for a DEC machine with 16 kB to get us around how slow the tapes and disks were.

We've certainly come a long way.

Now where's those MP3 players and high end phones with 1 TB of storage? I don't need on yet (everything I want to put onto one, today, would fit within 64 GB), but in time I can see wanting 1 TB or more in my pocket.

Dude, I totally win the C64 war.

I had my C64 with me when I went to college. During the take-home final exam for Finite Math in my first semester, I got too lazy to properly look up the way to do a particularly funky solution, but it occurred to me that I could approximate it pretty easily.

So I wrote up some C64 BASIC to do some really simple arithmetic, and iterated it like 1,000 in a DO loop. Put my approximated result on the test, and handed in my ~10 lines of code for my "proof". Got half-credit on that answer...

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.

2TB? That is still sometime away. Were not even quite there yet on the Hard Drive front. Let alone this new SDXC format, I think were only entering the arena of where 32GB SDHC are finally somewhat affordable in the 150-250 CAN range.

That amount is mind boggling.

Well I expect 64GB SDXC cards to be price at 300-500 CND minimum then at first whenever they appear though it truly depends on how much 32GB SDHC cards are at he time...

That might sound fast, but if you actually had a 2TB drive using that interface speed, it would take probably a whole day to read or write the entire flash drive. I don't think too many users would be pleased with that kind of speed.

For the math impaired...

104MB/s = 6.2GB/min = 374GB/hr = 2TB in 5.3 hours

A 3x improvement brings the time down to 1.76 hours to read all 2TB.

The 104MB/s is only "peak" or "maximum" data transfer rate. The actual sustained transfer rate will be much slower, hence my "whole day" approximation.

Well... tell me how many hard drives have the ability to write constantly at no less than 100mb/sec.

And the article says that the first sdxc cards will work at that speed, but it says nothing about the size they'll have, and I'd bet they'll be nowhere nere 2tbs.

People, remember this is just a specification... I think that before or as soon as those 2TB, 300mb/s cards come into production, an SDUXC card standard will be replacing this one.

For now, we simply have little use for a card with such a high reading speed:

An USB2.0 high speed SDXC reader will be flooded before reaching its 60mb/s max theoretical speed (480mbits/sec).

My point, which I think you understood, is that there is a mismatch in the specification between the maximum permitted media size and the maximum transfer rate. It doesn't improve the utility of the product much to increase one and not the other.

More like lossless encoding. I have my entire CD collection in 320kbps MP3 and it's under 100GB. When TB drives are in the $100 range, it's not really an issue. Only the quality stuff I save in lossless format, and that's less than 5% of my music. 95% is really disposable.

Digital photography and HD video is what now eats HDs. I can snap away a GB worth of pictures with my new DSLR in a matter of minutes. AVCHD also takes up a ton of space.

I am sure video / photography pro's wouldn't mind at least 10TB or even 100TB drives.

Having your MP3s at 320kbps really isn't worth it. If you're archiving up your collection, you should rip everything to lossless, and as you say, nowadays music, even in lossless format, isn't really an issue for hard drive space. Meanwhile, 320kbps CBR is overkill if transparency is sufficient for you. Most likely, 192kbps VBR will be sufficient.

If I may put in a shameless plug, might I suggest using FlacSquisher?

It's a program I wrote to convert my music collection from FLACs, which I keep for archival purposes, to Oggs, or MP3s, for use on portable devices (like my Rockbox'd Sansa). I use Oggs myself, because they handle gapless playback better than MP3s.

Meanwhile, 320kbps CBR is overkill if transparency is sufficient for you.
On the other hand - and the OP's point - is that disc space is so cheap, why not use 320kb/s? If you save a GB, you've only saved $0.25 worth of storage - so who cares about that?

Heck, HDD space is so cheap now that you could reasonably save your entire music collection in lossless, plus also in a couple of MP3 bitrates.

That's what I do, myself. Rip to FLAC, use FlacSquisher to convert to Oggs, keep both. I listen to the FLACs at home, and the Oggs elsewhere.

My point was that if he isn't concerned with the space his music is taking up, then he may as well rip everything to FLACs. If he is concerned with the space his music is taking up, then he should rip to a smaller bitrate. For example, the 95% of his collection that he considers "disposable" would take up much less space if it were in MP3 or Ogg format at 192kbps VBR, rather than 320kbps CBR.

320 is an overkill. If youre going that high, then just go lossless. It would be in the 500-600 range and much better for archiving. Convert them all later to 128/160 for portable listening. 192 is even an overkill unless you have a massive good system. AAC is much better at the same bitrate as mp3 so even 128 would be usually crisp.

Yeah, I do have high end equipment (Theil speakers powered with an Integra DTR6.8), so I can hear the difference. 320 does sound better than 192. I like at least reasonable sound quality for even the disposable stuff. The other 5% is lossless or played off the disc.

Some new CDs however are poorly mastered and even off the disc they sound like crap. One example is Nelly Furtado which made me think something was wrong with my equipment. Well, it sounded just as horrible on $50K of stuff at the audio shop. Now Louis Armstrong, Jerry Refferty, or Dire Straits, those sound incredible.

Exactly...I think the most I've seen on sustained disk to disk transfers have been 80-90MB/s on two (newer) 7.2k rpm SATA II drives. But I've seen 55MB/s copying from a 8GB sandisk Ultra SD card to the HDD - and that was weird since it was plugged into a usb 2.0 card reader. Considering these are used for storage if the real speed is anywhere close to 104MB/s then it's all good.

Ultimately either the HDD or the flash memory is going to be the bottleneck right?

There are some camera systems on the drawing boards that have raw data rates of almost 40 GB per second. Memory bandwidths still have a long way to go to catch up before we can use "standard" commercial-off-the-shelf memory hardware. It's coming along, but we need a factor of more than 10 improvement.

My new Canon Rebel XSi takes shots in RAW+JPEG at 3.5fps. RAW images are about 12MB, and the JPEGS about 4-5MB. So 16MB*3.5/s = 56MB/s. Yes, I use a class 6 card, but at 20 or 30MB/s it is still a bottleneck at some point unless I use just JPEG mode.

Now 40GB/s??? Yeah, that's insane.

RE: Transfer Rate
By strikeback03 on 1/7/2009 2:30:37 PM , Rating: 3
The reason you can only take a few images at that speed though is that the buffer fills up, and the camera cannot write to the card at the same speed it can shoot at. DPReview measured transfer rates of around 9MB/s. They also stated the maximum RAW+JPEG rate for their test sample was 2.5fps.

I think I said BD's death is on the horizon a few months ago. Now with the 32GB spec limitation gone, it's only a matter of time (and probalby not that far off) before it will make more sense to put a movie on a "postage stamp" than on a disc. The music industry is already considering replacing the CD with SD.

The only real issue may be shelf life. I'm not sure which is better yet: solid state, or non-writable/OEM optical.

I cannot wait until these things are available. Offsite backup will become much easier. Right now I lug around an external harddrive to work with my pictures, music, video, etc. about once per month. You know, in case the house burns down. But I do not have 2 of these. So one day per month there is a chance I could lose near everything. Backing up to DVD would require too many discs, and BD, well, it seems too expensive. Again, I cannot wait for even several hundred GB cards.

There is a significant price difference between pressing a CD and making an SD card. The problem is that the former is cents - and the cost of pressing bluray will drop to cents as well, whereas the latter is probably a dollar for a 1GB card. Problem is that it will always be a dollar, you'll just get more storage on it. Bonus is that non-sold albums can be rewritten instead of trashed - but probably cheaper to throw them away still.

Now a 2GB SD card with a 24-bit 96kHz (good-as-) lossless album and a 256kbps AAC for the portable player would be really handy. Let's get away from archaic CDs with their bitdepth issues with heavily compressed (audio, not file) music like Death Magnetic. Time to move to a new format I say, and maybe the mechanical CD's day is up. No more CD players to go wrong...

And yes, I think that SD is a viable competitor to BluRay in the long run (maybe Sony should have left the slot in all PS3s!). I'm not sold on digital downloads being the immediate future replacement for physical media however.

Actually it's even more than 40. If you've ever ripped a blu-ray movie, the main .m2ts file is anywhere from 20gb - 35gb on average. Remove the foreign language audio tracks and you've got a ~15 - 20GB file. Downconvert DTS-HD / DD True-HD to 5.1 AC3 and it's even smaller. I routinely make 720p / 5.1 ac3 .m2ts files to play on my PS3 off an external 500gb hdd. I keep 'em at 4gb (fat32 limitation), but man these things eat space. 2TB on flash memory would rock!

Unlikely, to say the least. Even if prices come down by 75%, a 32GB SDHC or SDXC card will still cost $25, and if a BR movie is on 2-layer media, its 50GB of data.

You'd need that 32GB SD card to be about $1-3 before movie companies would even consider it releasing movies on that instead of a spinning optical disc.

You're looking at 7-10 years before solid state mediums are both large enough and cheap enough to start distributing media on.

You're forgetting the MAJOR point, that blu-ray discs are going to be FAR more cost effective.

SDXC needs matching port.
By teckytech9 on 1/7/2009 3:00:58 PM , Rating: 2
The new SDXC specification provides up to 2 terabytes storage capacity and accelerates SD interface read/write speeds to 104 megabytes per second this year, with a road map to 300 megabytes per second.

Current USB 2.0 and Firewire rates won't match the speeds offered in 1Q 2009.

(USB 2.0) rate of 480 Mbit/s (60 MB/s)
(FireWire 400) rates to 393.216 Mbit/s (49.152 MB/s)

Test show that FireWire performs better than USB 2.0. Assuming that a large file needs to be transferred, the sustained rates are usually half or less than the theoretical maximum. Hence, the upgrades needed to the ports are:

(USB 3.0) rate of 5.0 Gbit/s (625 MB/s)
FireWire 3200 rates to 3144 Mbit/S (393MB/s)

In the interim, eSATA (300MB/s) seems to be the better option to utilize these SDXC cards. Assuming one can utilize these cards for external storage then eSATA has the S.M.A.R.T advantage. The only drawback is the absence of power and lack of accessible eSATA ports on older PC cases. I'd assume that one could find a vacant SATA port on their motherboard, and remove a rear metal latch and attach the SATA cable accordingly.

Perhaps this paves the way for thumb drive makers in designing rechargeable devices using future SDXC cards. The SATA 3.0 standard is just around the corner too.

I was reading this and with the transfer speeds, even at the low end they talk about first , would it not be possible to make a card, plugged into a pciex1 or x4 slot to hold a few of these sd cards? I remember a while back (couple years I think) reading about pci cards that hold ram to be used as a super fast hard drive. To me this would be amazing. To buy 3 or 4 of these cards, plug them into the card in your computer, or even to a slot int he front of your tower, and use them as your drive. Not just as basic backup or something but for system or transferable storage.

Am I missing something or is this actually a possibility?
