Kanguru has announced the availability of a rather novel pendrive featuring both USB 2.0 and eSATA 3Gb/s connectivity, with a surprising difference in performance between the two.

What happens if you connect both ends at once?

It creates a vortex in the space/time continuum, which will eventually swallow all matter and destroy the universe.

Alternatively, it simply chooses whichever connection initialised first - which is likely to be the eSATA port.

It explodes.

Nice gadget but pretty expensive. Although... is it bootable? It's not, right?

Can't think why it wouldn't be - BIOS support depending, of course. Heck, my no-name 32MB USB1.1 pendrive boots just fine - and an eSATA device appears to the system as a standard SATA drive (heck, if you use the included bracket adapter it /is/ a standard SATA drive, as that connects to a normal internal SATA port on the motherboard.)

Unlike USB eSata does not provide power right? So for use with eSata you would need the usb cable plugged in aswell I would assume.

How come it can read through eSATA at 75 MB/s but only 30 MB/s through USB? I guess what I mean is, I know there are bus overheads etc., but why does USB 2.0 (which is rated at 480 Mbps = 60 MB/s) seem to limit a flash drive which is demonstrably capable of reading at 75 MB/s to just half the rated bandwidth of the USB connection?

Actually, eSATA does have power that passes through... very little, and about nothing compared to USB, but it would seam to be enough for this pen drive. Also you must remember that without power at all, then no data can be transferred, as data is electricity.

It's using a proprietary esata connection that provides power, you actually must use the included bracket as it adds the power to the esata connector.

huh well this is certainly interesting, so they are using the new eSata standard that combines both power and data unlike the current eSata standard which is just data. I wish we would make the move to that standard sooner so it would makes sooo much easier and require less cables....

sweet.. I wish this was cheaper though
