Your top choice: Buffalo Ultra High Speed Flash Disk RUF2-S4GWH is not available through the manufacturer Buffalo. Nor does anyone online sell it. The part number is all but non-existent on Google. I'm wondering how you got your hands on one without the package, then put a picture of the package in the article? Did Buffalo provide the unit for your testing? If so, when will they start showing up at retailers? Thanks for the review.

Hope you can test the newer Corsair products, I see they released a model (CMFUSB2.0-8GBGT) which apparently does 34MB/sec and 28MB/sec read/write. It's not a paper release either as it is IN STOCK in a store local to me:
