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.

Got a super-fast Canon 5D MkIII? Love that you can just pop out the SD card and slide it straight into your Retina iPad via the camera connection kit? Not so fast – literally. Photographer Jeff Cable has done the math and found that the camera’s SD slot is slow, slow slow compared the the CF slot, and then it actually gets worse.
Wahoo's low-power sensor should last as long as a regular cyclocomputer.
There are probably hundreds of apps that will turn your iPhone into a mobile fitness device, using the phone’s GPS to track your speed and from there derive calories burned, route taken and so on. Some of them even connect wirelessly through a dongle to heart-rate monitors and the like. It’s like having a coach in your pocket, only he doesn’t wake you up in the morning by shouting at you.
Now, though, things are going to the next level. Wahoo’s new Blue SC speed and cadence sensor talks direct to the iPhone via low-powered Bluetooth 4, letting it communicate directly with your bike.

IOS runs HTML5 games a crazy three times faster than Android, according to a study by Spaceport.io. The tests were run on various hardware and software combinations, both for Android and iOS, and the results are pretty startling. And there’s an even more amusing data point: The Blackberry Playbook beat every Android device.
If Sprint’s new “network enhancements” were designed to quiet complaints by iPhone 4S users, the nation’s third-largest wireless carrier may need to return to the drawing board. Following tweaks for peppier 3G downloads, many Sprint customers still complain of turtle-like connections while lusting after Verizon’s faster network.
Want the iPhone 4S but still unsure which carrier to commit to? It was easier when there was just one, right? Well maybe this will help you decide: A test performed by Metrico Wireless highlights the strengths and weaknesses of all three iPhone 4S providers — AT&T, Sprint, and Verizon — with Verizon coming out on top when it comes to reliable calls, and AT&T beating the others to faster data.
After months of anticipation, Amazon’s $199 Kindle Fire started shipping yesterday, but even since its unveiling critics have been labeling it a worthy iPad competitor. Its pocket-pleasing price tag coupled with its terrific user interface could make it the first tablet to really give the iPad something to worry about.
But how does it stack up to Apple’s device in terms of performance? Well, at less than $200, none of us expected the Kindle Fire to really match the iPad 2’s speed, but as you’ll see in this video comparison, it does a fantastic job of keeping up while browsing the web, and it’s significantly quicker and streaming Netflix videos.
