We already saw A-DATA unveil what it claimed was the "world's first" 16GB SDHC card in the Class 6 family, and now Transcend is hitting us all up with a very viable alternative. The card guarantees a minimum write speed of 6MB/second, includes ECC to automatically detect and fix errors and sports a lifetime warranty, too. Not a lot to say beyond that -- especially considering the glaring lack of a price or ship date -- but we doubt you'll be waiting too much longer before seeing this on store shelves.

16GB SDHC cards aren't all that atypical these days, but A-DATA is claiming to have the "world's first 16GB SDHC Class 6" iteration ready to roll. Additionally, the firm is introducing an 8GB Super SDHC Duo (saywha?) card of the Class 4 variety, and for those still scouting a new CompactFlash card, it's cranking out a 32GB version for you. Regrettably, we've no idea how soon A-DATA plans to get these on the market (nor how much it plans to charge), but it shouldn't be long before we all find out.

Although Kingston's latest trio of 4GB miniSDHC cards aren't first on the scene per se, that Class 6 iteration is sure sitting at the head of the class. Partnered by Class 2 (2MB/sec) and Class 4 (4MB/sec) versions, the Class 6 miniSDHC card boasts an impressive minimum sustained data transfer rate of 6MB/sec, which ought to be more than sufficient for those unexpected video captures on your mobile. Most interesting, however, is the pricing scheme for the aforementioned devices, as the 4GB Class 6 card runs just two bucks higher ($66) than the Class 4 version ($64), and a mere four dollars more than the lowly Class 2 ($62) sibling, so it's a pretty safe bet that you'll be going for the speed on this one.

Sure we've seen 4GB and 8GB Class 6 SDHC cards before -- Lexar's got a pair, as does Transcend -- but when it's SanDisk that steps up to the plate with new Ultra II and Extreme III models, well, that's certainly worth a mention. As we're all well aware by now, Class 6 cards have a minimum sustained write speed of 6MBps, though both the 8GB Ultra II and 4GB Extreme III easily surpass that, clocking in at 9MBps and 20MBps, respectively. Available in June -- along with the new 4GB EIII Memory Stick PRO Duo card -- the 4GB EIII will retail for $180, the 8GB UII will fetch $240, and both models will toss in a "free" MicroMate USB 2.0 reader.

Toshiba's got a new series of "high-speed" and "ultra high-speed" SD cards coming to market soon, and although the company claims to be the first manufacturer to introduce these so-called Class 6 cards, we think it may be exaggerating just a bit. You see, the SD Card Association recently adopted three different speed classes (2, 4, and 6), with the class number indicating the card's minimum transfer rate in megabytes per second (i.e. Class 2 cards will always transfer data at at least 2MB/s). So although Tosh's ultra-high speed cards sport a zippy transfer rate of 20MB/s -- categorizing them as Class 6 cards -- we've already seen products on the market from ADTec that boast similar speeds (and waterproofing to boot); therefore, how can Toshiba claim that its Class 6's will be the first to launch? Marketing hyperbole aside, both the high-speed Class 4 cards (with 5MB/s transfer rates) and ultra high-speed Class 6 cards will come in 512MB, 1GB, and 2GB varieties, and you can expect them to drop in Japan in October and worldwide in November.
