never used Kanguru's products, we've heard of them in the past and their latest thumb drive is something that we're sure a lot of people will be interested in. The company has created a model which has a USB 2.0 port in one end and an eSATA port in the other.
The eSATA interface will allow for some greatly improved transfer speeds compared to using the USB port on the same drive, although you will have to use an additional dongle to power the thumb drive when you're using it with eSATA, which is a drawback.
Using the Kanguru e-Flash over USB 2.0, Kanguru quotes read speeds of 30MB/s and write speeds of 20MB/s, while it more than doubles the read performance when connected via eSATA, with read speeds of 75MB/s and write speeds of 25MB/s.
It also comes with a bracket that you can attach to your desktop PC that is also meant to power it, although as the company hasn't posted any pictures of this bracket, or the dongle for notebook use, we're not sure what these look like.
At US$84.95 (€68/£57) for a 16GB drive and US$119.95 (€96/£81) for a 32GB and a 64GB model coming out next year, it seems like the e-Flash should be able to find a home with a few performance users.
