How We Tested : We ran all test with the parkway touch base to a dual-2.5GHz Power Mac G5 with Mac OS X 10.4.8 installed and 1 GB of RAM . We examine the drive using FireWire 800 and eSATA . We copied a folder containing 1 GB of data point from our Mac ’s hard drive to the external hard drive to test the drive ’s write speed . We then repeat that file on the outside drive to test both read and write speed . We also used the campaign as a lolly disk when running our low - memory Adobe Photoshop CS test . This trial run is a set of four tasks do on a 150 MB file , with Photoshop ’s memory set to 25 percent.—Macworld laboratory examination by James Galbraith and Jerry Jung
