Newer Technology (NewerTech) today launched a new, enhanced version of its miniStack V2 combo external storage device that operates quieter than the previous model. The miniStack external FireWire 400/USB 2.0 single-drive solution integrates three USB 2.0 port and two FireWire powered ports in a Mac mini-like enclosure. A new construction process that incorporates a large aluminum passive heat sink serves to radiate heat away from the hard drive, resulting in quieter operation. The heat sink contacts the drive on both the top and side to disperse more heat, and an intelligent cooling system initiates a quiet protective fan only as a precautionary measure, according to the company. All models between 160GB and 750GB feature the latest Seagate Barracuda 7200.9 and 7200.10 mechanisms with a five-year warranty.
