From the manufacturer:
When it comes to raw power there is nothing to beat the dual-bay Taurus. This multi-bay hard drive enclosure is built strong and rugged, offering more than enough capacity to store all your digital media files. Not only that, the Taurus can also back up and secure all of your data thanks to RAID protection. Great performance, great protection and great looks - only in the Taurus.
The Taurus is designed to house two 3.5" SATA hard drives with the option to setup your drives and combine them as one single volume or even using RAID. They are mounted to the enclosure with a silicone rubber ring to prevent vibration and reduce noise. The ON/OFF switch and LED status indication are located conveniently at the front of the enclosure for easy access and good visibility.
The Taurus comes with a versatile interface, featuring eSATA, FireWire 400, FireWire 800 and USB 2.0 High Speed. To increase performance and data throughput, the "RAID 0 - Striping" setup will be ideal for your daily backup and other data transfers. For important data and reliability, the "RAID 1 - Mirroring" setup will be the best solution, automatically creating a copy of all the data in case one of the drives fails. To keep your drives cool, the Taurus is using a smart fan, which automatically regulates fan speed according to the internal temperature.
