Getting the flexibility of external hard drives combined with the security of a RAID array has never been easier! Mediasonic’s HFR2-S3B accommodates four 3.5’’ SATA I/II hard drives, and each drive can be up to a whopping 2000GB. It connects to your PC with Windows or Mac OS through hot-swappable USB 2.0 or eSATA connection as well as FireWire 400/800 ports.

You will never need to worry about your hard disk drive malfunctioning with the RAID technology. The Mediasonic HFR2-S3B integrates a hardware RAID controller to support RAID 0/1/3/5/10 configurations while reducing the load of the server. A RAID control button makes the setup easy. A smart fan with auto/manual mode and 3-level speed combines with the built-in thermal-sensor to keep the drives cool and running at peak levels.
