A deal today lists the Lexar 32GB Class 10 SDHC on sale today, making it even cheaper than the Transcend brand 32GB SDHC card. Other sites are still holding on to the almost $60 dollar price tag. The new sale price still comes in slightly cheaper than the promotional (2) pack 32GB Lexar deal, so if the Lexar name brand turns you on, you can find the current sale price of just $35.99 dollars following the link (click here).
Some people swear by shooting only cards that are 8GB in capacity Max. I shoot with 32GB cards, call me a Danger Seeker. Some people shoot only Sandisk media. I personally shoot with the Transcend Class 10 or 400x Media Cards.
Regardless of anyone's rhyme or reason you can grab a Sandisk 8GB SDHC Class 10 for an awesome price over at B&H much cheaper than elsewhere. As for the Transcend 8GB Class 10 (which isn't as fast, but fast enough for video) you can find those running under $12 dollars. Links below.
If you're wondering about what the 128GB Lexar SDXC card is good for, there's a number of things. Besides throwing it into bitrate hungry high end cameras, another good purpose is doubling the disk space on my MacBook Air. The new Macbook Air can't be upgraded internally, so by using a very generic SDHC card reader, i'm able to double my storage with a solid state drive that can transfer 100MB files in less than 7 seconds. There's no limit to individual 4GB file sizes with exFAT format and the card works both on Mac and PC. It's the smallest and lightest storage media I can carry in my backpack. If you're looking at 128GB USB thumb drives with equivalent speeds and you'll find yourself coughing up about twice the price of this single Lexar.
So, since the Lexar 128GB card is based on exFAT file system with no 4GB limit, what happens if you place it into a Canon 60D? Will the video stop automatically? The answer is yes it will stop at just around a 4GB file size - so DSLRs won't be taking advantage of SDXC and larger file sizes (for now). The Canon 60D and Panasonic GH2 can see the entire 128GB and can record video without any buffering issues, but for now the card is a bit overkill. For other things like being able to dump files to the editor, run backups in Time Machine, or use it for additional storage it's pretty quick and has a feather weight footprint in the bag...
That sexy new Lexar 128GB SDXC Card is now shipping (first metioned here: http://cheesycam.com/lexar-sdxc-media-cards/). The fact that this comes with the name Lexar at the introductory price is already exciting. Interesting that on Lexar's own website, the Buy It Now price is $80 dollars more than at B&H. Sounds expensive upfront, but those who remember having to pay over $1,000 dollars for a very small amount of sxs Memory feel the deal.
Sure it's not something DSLR shooters will go nuts over, but there's plenty of higher end cameras that can take advantage of these new Extra Capacity cards. Of course the newly announced Sony NEX-FS100E could benefit, but even other cameras like Canon's XA10 Pro-Sumer video camera would be a nice home, since it has a feature to use Double SDXC card slots and record simultaneously (for redundancy). Maybe an sxs adapter will be available to fit the new Sony PMW-F3 and take some of the cost of ownership down a bit. I'm just more curious to see if a Canon T2i can see that much 128GB memory..
[Update] For those who questioned the demand on such high priced media, it just sold out in a few hours. About two weeks out, but you can still order.
