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.

Last week I wrote a few tips about disk encryption, but I didn’t write about what to do with the startup disk on your Mac. I cannot think of any reason you shouldn’t encrypt your startup disk after the release of Mac OS X Lion. Apple has made it just to easy for you to encrypt your drive.  It is quick, fast and easy. I’ll show you how today.

If you are planning on using Target Disk Mode to boot your Mac equipped with Thunderbolt ports you’ll need Apple’s special Thunderbolt cable in order for it to work. This is required even when connecting two Macs or a Mac to an external Thunderbolt equipped disk drive.

One of my biggest concerns about Apple distributing Mac OS X 10.7 Lion via the Mac App store has been resolved. One intrepid Lion beta tester has discovered a hidden secret inside of Lion’s installation application.

Every once and awhile, your Mac will decide not to eject a CD or DVD, for various reasons. It could be that it can’t detect the disk, it’s in an incompatible format, or that the disk itself is locking up the computer. But, no matter the reason, here are some quick fixes for ejecting stuck CDs and DVDs.
