LAS VEGAS--Lexar plans to introduce faster, higher-capacity CompactFlash cards using a new generation of the flash memory technology, a company executive said Wednesday.
Lexar's top-end 300X cards will be outpaced by new models shipping later this year.
(Credit: Lexar)Lexar's current top-end 300X-rated CompactFlash cards use a standard called UDMA (Ultra Direct Memory Access) to transfer data at 45MB/second, and their capacity tops out at 16GB. But using a new generation of the standard, UDMA 6, Lexar will release cards that have significantly faster transfer speeds and larger capacity, Jeff Cable, director of marketing, said in an interview here at the Photo Marketing Association (PMA) show here.
Cable wouldn't be pinned down on precise details, but he said the new cards' capacity "probably" would be 32GB, and their transfer speeds likely would "pretty close to" UDMA 6's threshold of 100MB/sec, which is more than double that of today's UDMA.
Only newer SLR (single lens reflex) cameras support current UDMA technology, but it's spreading, and there are benefits. For example, cameras can take longer continuous bursts of photos, and photographers can zoom faster to check focus when reviewing shots on the camera LCD. Video, which is arriving in new SLRs, also can saturate data-transfer pathways.

The new version, called CFast, has faster data-transfer speeds that could let photographers take more continuous shots without waiting for the camera to catch up, cut camera makers' costs for built-in buffer memory, and make it swifter to review photos on a camera or copy them to a computer.
This a closeup of the a CFast-era CompactFlash card. Note that it's got a slot instead of pins and that it's got different ridges called keys down the sides to prevent it from being used in today's style of CompactFlash slot.
(Credit: Stephen Shankland/CNET News.com)"It's going to end up in the high-end cameras. The reason to move to it is purely for speed," said John Santoro, senior product marketing manager for Lexar, a flash card maker and Micron subsidiary. He predicts its arrival in 18 to 24 months. "It's my feeling the camera companies already have this on their road maps and want to start working on prototype samples as soon as the specification is finalized."
But as with many upgrades, the standard will break compatibility with today's technology. That means today's CompactFlash cards won't work in CFast slots, and CFast cards won't work in today's slots.
So the more certain you are that you'll buy a new high-end camera in the next couple years, the more cautious you should be before investing in an expensive collection of shiny new 32GB CompactFlash cards.
CFast spec almost done; prototypes to come
Last year, the CompactFlash Association began work on the new standard, and the specification is in its final stages, said Bill Frank, executive director of the CompactFlash Association.
"We expect the CFast specification to be published for distribution in the second quarter--hopefully in April or May," said Frank, who showed off CFast prototype cards and slots at the Photo Marketing Association trade show last month in Las Vegas.
Top-end CompactFlash today cards reach 45MB/sec, a speed rating also called 300x (1x is 150KB/sec). CFast, though, uses an interface called Serial ATA that today reaches about 375MB/sec.
In practice, today's cameras can't keep up with those speeds, and flash card readers struggle when transferring images to computers. But faster speeds are useful in cameras, as newer SLRs show: when data can be written to a flash card faster, it's easier to design faster burst-shooting modes into camera that otherwise must rely on more built-in conventional memory.
CFast cards have a different electronic signaling technology that requires a different physical interface, and cards and sockets are shaped differently to prevent people from mixing the older and newer cards. The new socket is tested for 10,000 insertions, just as with current CompactFlash, Frank said.
Camera adoption?
The next question is how CFast will arrive in cameras. CompactFlash today is used in higher-end SLRs from Nikon, Canon, Sony, and Olympus. But camera makers are reluctant to describe particular technology plans, and Nikon didn't even respond to a request for comment.
When I asked Chuck Westfall, technical adviser for Canon USA's professional products marketing division, whether CFast would catch on, he was equivocal. "It remains to be seen. What drives the market is cost and performance issues and availability," he said. Canon's caution, for example, meant it only moved its low-end Rebel SLR line to SD flash memory when the card format was very well established.
Richard Pelkowski, digital SLR product manager for Olympus America, also wouldn't commit, but he did acknowledge the general advantage of CFast. "Greater speed and greater capacity--we certainly realize the benefit of that," he said, adding that card speed not only lets images be written faster, but also lets photographers review them more easily and take advantage of features such as the side-by-side comparison in Olympus' new E-3 SLR.
SanDisk, another top flash card maker, was more circumspect than Lexar.
"At some point, the industry is going to have to transition to some other type of high-performance card," said Jonathan Hubert, SanDisk's director of strategic marketing for flash cards and accessories. CFast is one strong candidate, he said, but then suggested that the SD Card Association isn't resting on hits SDHC laurels.
Frank, perhaps unsurprisingly given his leadership at the CompactFlash Association, was the most bullish of all. He said that Canon and Nikon engineers are participating in the CFast specification development and that the first cards likely will hit the market in the second quarter of this year. "Since this affects the silicon (chips) in cameras, expect no less than a year for cameras to appear using CFast," he said.
Jump-starting the market
If it were up to the camera makers alone, CFast's future would be more uncertain. But there are industrial uses of CompactFlash, too, for computing devices embedded into all manner of things.
CompactFlash is used in routers, defibrillators, Apache attack helicopters, and General Electric locomotives, Frank said. Some slot machines have two--one for holding the operating system and another for logging transactions.
The CompactFlash future in some ways isn't hard to predict. The technology uses the same interfaces as conventional computer hard drives, and it's been following that road map with a few years' time lag.
Today's mainstream CompactFlash cards use an interface called IDE or parallel ATA, and a newer generation just arriving use a speed bump called Ultra Direct Memory Access (UDMA) that in practice tops out at about 80GB/sec. The CFast version uses Serial ATA technology, which was announced in 2001 and connects hard drives in virtually all PCs today.
Those industrial computing customers, who often don't suffer the power-consumption constraints of camera makers, are eager for the new technology, Frank said--indeed, they were the first to ask for it. Because they're using conventional SATA computer chips, it's not difficult to move to the new technology.
From there, it's a matter of jumping to the camera market, where Lexar focuses. "I think it's inevitable," Santoro said.
Panasonic's 32GB SDHC card, with a 20MB-per-second transfer rate, will cost about $700.
(Credit: Panasonic)Panasonic announced a new SDHC (Secure Digital High Capacity) flash card on Tuesday that offers both high speed and lots of space for those willing to pay.
The 32-gigabyte card, called the RP-SDV32GU1K, is due to ship in April for about $700. It's a high-speed "class 6" card that can transfer data at speeds of 20MB per second--the world's first at the 32GB capacity, Panasonic asserts.
SD is the dominant format for flash memory, and with the newer SDHC technology that extends capacity beyond 2GB, it's begun spreading into space-gobbling videocameras. SanDisk, a top flash card brand, announced a 32GB SDHC card costing $350 in January, but it transfers data a notch slower, at 15MB per second.
One major flash card alternative to SD, CompactFlash, can transfer data at a maximum of 45MB per second. However, top transfer speeds are often more useful when copying files from a flash card, since cameras and videocameras often can't write data at those top speeds.
SanDisk's 32GB Ultra II SDHC card will cost about $350, including a USB card reader, when it goes on sale in April.
(Credit: SanDisk)Correction 10:00 a.m. PST: This blog initially misstated the speed at which SanDisk's top-end Extreme Ducati cards can write data. It is 45MB/sec.
LAS VEGAS--SanDisk, one of the best known makers of flash memory cards, has started making the jump to 32GB capacity.
The company announced its 32GB Ultra II SDHC card Thursday at the Photo Marketing Association trade show here, a model designed with the needs of flash-based video cameras.
It will cost about $350 when it goes on sale in April, the company said. A $180 16GB Ultra II card will be available in March, and both come with a MicroMate USB card reader.
In addition, SanDisk announced a $100 8GB Ultra II Plus card. It hinges open to reveal a USB plug that lets the card be directly connected to a computer.
All the new cards can write data at 15 MB/sec, a notch up from the 9 or 10 MB/sec of earlier Ultra II models, SanDisk said. However, that's not as fast as CompactFlash models, where SanDisk's top-end Extreme Ducati cards reach 45MB/sec.

(Credit: SanDisk)SanDisk spokesman Ken Castle wouldn't comment on when the company's 32GB CompactFlash cards might reach the market. Competitors PNY and Transcend announced their 32GB CompactFlash cards in January.
"We've chosen to go with the SD first. That's where the momentum has been," Castle said. "Camcorders with HD (high-definition video) can eat memory pretty quickly."
SanDisk in 2007 sued 25 flash-card competitors, including Transcend and PNY, alleging patent infringement.
Canon's EOS Rebel XSi goes on sale in April.
(Credit: Canon)Canon faced some modest compatibility risks when it chose to design its new EOS Rebel XSi camera with SD flash-memory cards rather than the CompactFlash cards it's used for all its SLR cameras until this point, but I think the move is smart overall.
It's a drag for consumers that there's such a profusion of flash card formats. Customers often must pay extra when moving from one camera maker to another just to replace flash cards. And indeed, owners of Canon's existing Rebel, Rebel XT, or XTi cameras will find their CompactFlash cards useless if they upgraded to an XSi.
But the reality is that Rebel XSi (also called the 450D and Kiss X2 in various parts of the world) customers are more likely to be upgrading from a compact camera, a market where SD dominates. And from a technical perspective, SD performs fine, takes up less critical room in the camera, and in the newer SDHC incarnation can match CompactFlash's 32GB capacity.
CompactFlash memory has been a mainstay in the SLR (single-lens reflex) camera market, but SD has gained a foothold. Nikon's entry-level SLRs use SD cards, as do all from Pentax, Panasonic, and Samsung. And Canon's top-end 1Ds Mark III accepts both SD and CompactFlash.
Now if we could just get rid of xD Picture Card from Olympus and Fujifilm and Memory Stick from Sony, we'd all be better off. Fujifilm wisely has started selling compact cameras with a dual-use adapter that can accept SD as well as xD, and I'm hoping that's a harbinger of things to come.
Correction January 27 7 p.m. PST: I messed up the photo-capacity math. A 32GB card can hold more than 10,000 3MB photos.
PNY's 32GB CompactFlash card should cost about $400 when it emerges in the second quarter of 2008.
(Credit: PNY)Jumping the Photo Marketing Association trade show gun by a few days, PNY Technologies announced several new 16GB and 32GB flash cards for cameras and video cameras on Thursday.
The 32GB SDHC card can keep up with high-definition video captured at 9 megabits per second, the company said. And the Optima Pro CompactFlash card, has a 266X transfer speed, or 40 megabits per second, using a UDMA interface.
Both cards will be available in the second quarter. The SDHC card should cost about $250 and the CompactFlash card about $400, though the company cautioned prices could change given volatility in the flash memory chip market. PNY purchases its flash memory chips from Toshiba, Samsung, Intel, and others, the company said.
Capacity of 32GB may sound like overkill for digital photography--that's enough to hold more than 10,000 3MB images--but there are reasons it's useful. Raw files, especially newer 14-bit files, have moved well beyond 10MB apiece, shooting in combination with JPEG adds even more, and trigger-happy high-end cameras that shoot 5, 6.5, 9, and even 10.5 frames per second chew through memory in no time. And, of course, flash memory-based video cameras need all the capacity they can get.
Transcend's 32GB CompactFlash card
(Credit: Transcend)PNY plans to show the cards at PMA along with new 8-inch and 10.2-inch digital photo frames and a 32GB USB flash drive, the company said.
Another company that's taking on better-known flash card brands such as SanDisk and Lexar is Transcend. It announced a 133X 32GB flash card earlier this month that includes support for ECC (error-correcting code) that can catch and fix some errors that sometimes occur when reading and writing data.
The Transcend card also supports UDMA access. (UDMA lets cameras write to a memory card faster, but only newer and higher-end cameras include the feature right now.)
Jobo's 200GB Giga One Ultra portable photo backup device.
(Credit: Jobo)Jobo on Monday announced the Giga One Ultra device, a portable hard drive for backing up photos in the field. That's a notch more spacious than the 120GB of the Giga One predecessor or the Spectator device, which unlike the Giga One devices have a color screen.
The drives have slots for a variety of flash memory modules, including CompactFlash, SD and SDHC, Memory Stick and Memory Stick Pro. Photographers can back up their data while on the road, an idea that's especially useful if you're running out of flash card space.
The new models can download data from flash cards more than twice the speed of the Giga One, Gummersbach, Germany-based Jobo said.
The Giga One Ultra is scheduled to arrive at the end of October with capacities of 40GB, 80GB, 120GB and 200GB and prices of $149, $199, $229 and $329, respectively.
