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…
