And for what? You're not going to add any performance, because the NAND used in these devices isn't fast enough to exceed the speed of USB 2.0.

The name is funny though.]]>Nov 19th 2008 11:55AMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/Nov 19th 2008 11:58AMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://en.wikipedia.org/wiki/ESATA#External_SATA

And it doesn't matter how fast eSATA is, if USB 2.0 can already handle the rates the NAND offers.

The NAND in these flash drives isn't fast enough to exceed the speed of USB 2.0. Not even close. If this is very well implemented, it could offer perhaps as high as 20MB/sec of throughput, and that's still 1/3rd of what USB 2.0 can offer.]]>Nov 19th 2008 12:33PMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/Nov 19th 2008 12:56PMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/Nov 19th 2008 1:07PMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/Nov 19th 2008 1:52PMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/Nov 19th 2008 3:24PMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/]]>Nov 20th 2008 2:15AMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/]]>Nov 20th 2008 2:16AMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/Nov 19th 2008 11:56AMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/

How will you reach eSATA performance over USB? That's right, you can't! I haven't really seen any hard drive enclosures that had eSATA, but never had a USB output on it as well.. And using your drives without an enclosure is just asking for trouble!]]>Nov 19th 2008 11:57AMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/Nov 19th 2008 11:59AMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/Nov 19th 2008 12:05PMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/Nov 19th 2008 12:07PMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/Nov 19th 2008 12:14PMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/Nov 19th 2008 12:16PMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/Nov 19th 2008 12:22PMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/
esata has its own port, it doesnt use USB.]]>Nov 19th 2008 12:25PMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/USB uses DMA (direct memory access). It doesn't use cross-device DMA (i.e. memory address mapping) but then again neither does eSATA. As far as I know, Firewire is the only major external bus that actually uses memory mapping for transfers. And to be honest, there's a reason. It's a massive security issue and it doesn't increase performance.]]>Nov 19th 2008 12:36PMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/Nov 19th 2008 1:22PMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/Nov 19th 2008 12:30PMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/Nov 19th 2008 1:34PMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/Nov 19th 2008 12:35PMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/
The difference is AMAZING. The thumb drive probably isn't smoking fast, but is 2-3 times faster on eSATA.]]>Nov 19th 2008 12:41PMhttp://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/http://www.engadget.com/2008/11/19/kangurus-new-e-flash-thumbdrive-marries-esata-and-usb/eSATA: up to 75 MB/s

So the flash is limiting you on the write still, but it looks like USB is limiting on the reads, which jives with what I've seen from SATA drives in different enclosures.

However, having said that, do most thumb drives max out the usb2 interface anyway?
Maybe this is more of a tiny external SSD, but I somehow doubt it based on the price.

*One end has the normal USB connector. The other has a new POWERED eSATA connector.
*Using the Powered eSATA connector plus the bracket and cable we include, you can hook this up to your desktop via the eSATA connector only, no added power cables needed.
*We are also offering a powered eSATA Expresscard for laptops very soon. In fact many new laptops by Dell, Toshiba, etc already have a Powered eSATA port on them now (called USB/eSATA i believe)
*The device is much faster through eSATA, our testing shows on average, 75 MB/s Read, 25MB/s Write.
*you can see the full Specs here (stated by Jay Evans). http://www.kanguru.com/eflash.html
