Seagate this morning reached another record for storage with a 1.5TB version of the FreeAgent GoFlex Ultra-portable drive. The disk is the first 2.5-inch drive to reach the density and still claims a possible edge in speed. It ships with a USB 3.0 cable that gives it a theoretical 5Gbps peak speed, and as a GoFlex drive it can switch to FireWire 800 or another high-speed format.
