My main computer is a Mac mini. This mighty mite takes up little more space than a paperback book but still provides the processing power of a tower drive computer. The appeal of the mini is its small footprint, but it's also currently limited to a maximum 500 GB hard drive. That's a lot of space but not enough for archiving a large digital library without compromising fidelity by compressing files. Enter Newer Technology's miniStack, a Mac mini body clone designed to sit squarely atop the computer, adding just 1.5 inches of height. Models up to 2 TB are available, with 1 TB units retailing for $189.99 on Other World Computing's Web site (http://eshop.macsales.com). These feature a 7,200RPM drive, one eSATA, two FireWire 800, one FireWire 400, and three USB 2.0 ports, and come with FW800/FW400/USB 2.0 connection cables. The miniStack V3 comes plug-and-play ready for both Macs and PCs. I test-drove a 250GB model and was impressed with its lightning-quick Firewire file transfer and quiet and cool operation. The Mac mini's FireWire 800 port, along with the miniStack V3, support transfer rates up to 800 Mbps. Considering that a standard compact disc at full capacity contains 700 MB of data, it's easy to see how such speed can make short work of a big project. For a Mac or Firewire-compatible PC, and particularly for use with Mac minis, the miniStack V3 is my speedy and spiffy choice.
