How Loud Are Your Mac's Fans?

When they get hot, Macs turn on various internal fans to keep components cool. The noise can be annoying, but just how loud is it? If you have an iOS device with a built-in microphone, you can download one of many free sound meter apps (search on decibel in the App Store) and see if you're subjecting your ears to a truly unreasonable noise level.

 
 

3.5" Erasable Optical Due

Send Article to a Friend

The first 3.5" erasable optical drive was announced recently by Pinnacle Micro Inc., which claims that the drive's average seek time is a mere 28 milliseconds, far below that offered by the 5.25" standard erasable optical disks. Each $129 disk will store 128 megabytes of information, less than the 650 megabytes that the 5.25" drives will hold. However, the list price on the drive is $2995, so street prices should be less than the $3500 or so that the 5.25" drives cost. Compared to a 105 megabyte Quantum hard disk, the Pinnacle erasable optical is still expensive at about $24 per megabyte, but adding additional disks lowers the price per megabyte significantly. For graphic designers who wish to store large 24-bit images or anyone who needs a large amount of storage, the Pinnacle 3.5" drive will provide it at a reasonable speed, unlike its 5.25" brethren.
