Designed for Mac, but works with Windows once you change the file system... actually all external Thunderbolt drives work with Windows provided your motherboard has a "certified" Thunderbolt connector & you change the file system on the external drive.

Due to price of Thunderbolt products, I still prefer USB 3.0 & eSATA III external devices. To that end, I use this http://www.shopaddonics.com/Itemdesc.as ... SP&eq=&Tp= along with a 128GB Vertex 4 SSD over eSATA III connection for transfer rates up to 400MB/sec.

Thunderbolt's only nice feature is you can daisy chain in series and it may provide enough power so you only need the cable. Otherwise, for hard drives, you would need RAID 0 with 6 drives on the fastest performing drive before you could claim you're using it for bandwidth. It's just too bad USB3.0 doesn't supply enough juice (4.5W at the most)... I can't wait for the USB spec to come out that can provide 100W (25W would be good enough for pretty much 99% of peripherals)

100W has been possible (though AFAIK never implemented) since USB 2.0 came out... My motherboard currently supports 10-12W on all USB ports including the 4 USB 3.0 ports, http://www.gigabyte.com/microsite/185/on-off-charge.htm & up to 30W on up to 3 ports (10W each) when shut down thanks to the 6 amps my PSU supplies over the +5Vsb rail.

From the official USB specifications:

3.1.1.3
The USB 2.0 PD Standard-B connector is defined to facilitate deliver of up to 100 Watts. An ID pin supports PD identification. Refer to Section 3.2.5 for mechanical details, pin assignments, and descriptions.

3.1.1.4
The USB 3.0 PD Standard-B connector is defined to facilitate delivery of up to 100 Watts. An ID pin supports PD identification. Refer to Section 3.2.6 for mechanical details, pin assignments, and descriptions.

This would suggest the document was revised then to include the 100W spec, which also includes USB3.0. So it was never designed to meet 100W from the get go.

Also I had a herp-derp moment. You don't want 100W from a 5V source. That's 20A, which you would need at least an 8 AWG wire to safely contain for USB cable lengths (http://www.engineeringtoolbox.com/amps-wire-gauge-d_730.html), and the USB cable by itself looks like 8AWG. The 100W is for 20V @ 5A.
