USB 3.0 PCI Card Installed in Tower–Backing Up Much Faster

I installed a PCI USB 3.0 card in my Windows 7 tower computer this evening, and am transferring a disk  image from an internal HD to an HD in a USB 3.0 dock. The image file is almost exactly 1TB, and if I copied it over a USB 2.0 connection to an external HD, it would take somewhere around 12-15 hours.

Over the new USB 3.0 connection, the projected copy time for the 1TB file was initially 3 hours and 15 minutes. After about half an hour, that's crept up to 3 hours and 45 minutes, but it's still way faster than over USB 2.0.

Installing the card was a bit of a challenge. It's a powered card requiring a SATA lead off the computer's power supply. When I first tried to install it, I was dismayed to find that I had no free SATA leads left. There were several IDE Molex available, so I ordered a 4-Pin IDE Molex to SATA Power Adapter Cable. That took a few days to arrive.

And when it did, it was too short! What's that about measuring twice and cutting once, or in this case, ordering?

I thought I'd just order a longer cable, but then I got to thinking. I have lots of power cable leads from old computers around, so I chopped the short 4-Pin IDE Molex to SATA Power Adapter Cable in half, and spliced in about a foot of extra cable.

And we have fire!
