LaCie is out today with the new d2 Thunderbolt 2 drive featuring a new design with a smaller footprint and an optional SSD upgrade for adding faster storage to the mix. The new LaCie d2 is an up-to-6TB hard drive spec’d at 7200 RPM with speeds up to 220 MB/s and two Thunderbolt 2 ports alongside a USB 3 port.
