A full 15 months after Panasonic dropped jaws with its 32GB Class 6 SDHC card, the company is hitting us up with another world's first. Announced today over in Europe, the outfit has revealed a new line of SDHC memory cards that boast a Class 10 speed rating. Said spec was recently given the green light as part of the SD Card Specification v3.0, and as you could likely surmise, the increase in transfer rates should enable the cards to better handle all that HD video your DSLR seems to be capturing these days. Still, the boost is relatively minimal (particularly compared to the forthcoming SDXC format), with Class 10 promising maximum speeds of 22MB/sec and Class 6 cards already offering top-end rates of 20MB/sec. Mum's the word on price, but Panny expects these to ship next month in the UK before heading to other markets sometime later.
