Kingston's New UHS-I U3 SDXC Cards Can Write at 80 MB/s
Kingston's new SD cards are Speedy!
Kingston has announced a new lineup of SD cards, which are rather speedy. They are to be known by the part numbers SDA3/16GB, SDA3/32GB, and SDA3/64GB.
The cards match the SD Association's newest specification, UHS-I U3, though go well beyond the required performance numbers. Kingston claims that the SD cards can read and write at 90 MB/s and 80 MB/s, respectively. The U3 specification guarantees you at least 30 MB/s for both reading and writing. Of course, to meet these speeds when accessing the cards from your PC, you'll need a USB 3.0 capable card reader.
The 16 GB and 32 GB models are based on the SDHC technology and feature a FAT32 file format. The 64 GB card is an SDXC card, initialized with the exFAT file format.
No word on availability or pricing yet.

Not a typo, those are BYTES per second, not BITS per second. They're insanely fast. But they currently cost an arm and a leg at about $185 for a 16GB card and just about double that for a 32GB card, and currently they can only be bought directly from Japan off ebay, but the point is you can still own one RIGHT NOW if cost is no issue.

Incidentally you can also get rewritable triple-layer (100GB) BD-RE XL discs off ebay (also from Japan) at similarly exorbitant prices, but again, they ARE available.
