Seagate today swept through its external hard drive line with a series of upgrades for just the Mac versions of its disks. Highlighting the launches is the FreeAgent Go Pro for Mac: the storage is one of the few wholly portable 2.5-inch external drives to include a FireWire 800 interface and also supports both FireWire 400 and USB. Every drive also spins at 7,200RPM and behaves more like a 3.5-inch drive in spite of its size. 250GB, 320GB and 500GB models ship this month at prices of $130, $150 and $190 respectively.

Regular, USB-only versions under the FreeAgent Go for Mac label have been upgraded and will ship in similar capacities for $100, $120 and $150. As a companion to these and the Go Pro, the optional Go Dock+ adds a three-port USB hub for those connecting a cradled disk using the same standard. It's already available and ships for $40.

The FreeAgent Desk for Mac now tops out at 2TB, up from the 1.5TB maximum before. It continues to have both FireWire 400 and 800 interfaces along with USB and sits on top of the existing range with a $340 price point.
