With still camera megapixel sizes increasing and camcorder manufacturer’s designing solid state HD video models, the demand for SD cards with greater file capacity is growing. And at CES, we’ve found two companies that are pushing the SD capcity envelope to it’s limits.

Along with their latest SD camcorder models, Panasonic has announced a 32GB SDHC card with Class 6 writing speeds. The new SDHC card will hold to to eight hours of standard high definition video at 1440 x 1080i resolution or just a hair over five hours at 1920 x 1080p full HD resolution. And at a Class 6 speed this SDHC card can scream with a data rate of 20MB/sec. In addition, could conceivably hold almost 6,000 still pictures at 12 MP resolution, that is, once still cameras firmware updates are written to accommodate it. No word on price yet, but you can bet it won’t be cheap. The good news is that it’s introduction will no doubt cause prices to drop further on 4GB-16GB models. It has a projected released date of Spring of this year.

And not to be left behind, SONY has also announced a 16GB version of it’s proprietary Dual Memory Stick Pro. No real details, other than it’s Memory Stick, which means it’ll only work on SONY products and will be available in March for around $300
