Seriously, outside of an airplane, I don’t think I’ve ever traveled at 207 miles per hour (or 333 kilometers per hour, if you’re metric).

Swiss cyclist François Gissy, however, just set a speed record on a rocket-propelled bicycle designed by his buddy Arnold Neracher.

How’s that for fast? Check out the video of the record-breaking attempt below, but be sure to turn down your sound. Nothing sounds as silly as a rocket bike.

How Fast Is That External Drive? Find Out With Disk Speed Test [OS X Tips]

Disk Speed Test

I’ve just picked up one of those fancy USB 3 drives to use with my Macbook Air as a sort of secondary backup when I travel, as it was so inexpensive for a 120 Gb drive. I wanted to know how much faster it might be, even on my non-USB 3 Air, than the run of the mill USB drive that you can pick up for a few bucks at the local electronics store, or get as a giveaway at a tech conference, for example. I also wanted to see how fast the new SSD drive that I installed in my Macbook Air was, just for kicks.

I wasn’t sure how to measure the relative speed of these drives, though, until I found out about Disk Speed Test from the fine folks over at OS X Daily. I was able to check the speed of my fast USB drive, my internal SSD drive, and an external USB-powered drive, and compare them all, which is pretty peachy.

Here’s how it works.
