This Sanwa 32GB Flash drive has a similar feature as Silicon Power 64GB Flash drive. They both have dual interface of USB and eSATA connector.
Sanwa 600-UZ16G(16GB) and 600-UZ32G(32GB) are the two models set to be released in Japan first. I’m not sure when this stuff is gonna come out of Japan, but it’s not always needed to wait for it. I believe manufacturers in US will start their quest into producing this type of Dual interface flash drive because beside it can double the current transfer speed, eSATA is also a raising trend in 2009.
No price detail on Sanwa flash drive yet, but it should be below $100.
