Quick Test: Seagate's 1TB Portable FreeAgent GoWilson Rothman10/10/09 10:00amFiled to: Hard Drives1Tb usb drive1Tb portable drive1TBSeagate1Tb seagate freeagent gofreeagent goHddWestern DigitalWDmy passport42EditPromoteShare to KinjaToggle Conversation toolsGo to permalinkThe season of the 1TB bus-powered USB drive is upon us. WD was first; now Seagate is shipping the FreeAgent Go, a chunky SOB—three platters worth of storage powered and connected by one skinny cable.The good news is that these things work well, despite the larger drive and lower power. They're not about performance—5400 rpm only—but when I tested moving a 1GB file to and from, I got it in under 30 seconds, just a hair slower than the same file moved to and from faster FireWire 800 drives. I didn't do any real benchmarking, but I am convinced that the USB is going to be the bottleneck, not the bigger drive (shown below with a 320GB USB-only and a 500GB FW800/USB combo). The FreeAgent was even designed to fit the USB dock and FreeAgent Theater+, though not subtly.
