The CADA-C32 Series offers an unbeatable combination of RAID data protection, a vast storage capacity of 1 TB (500 GB mirrored), and ease of use with a Mac. This dual-bay drive features swappable hard disks and a built-in RAID chipset controller and arrives preconfigured in RAID 1 to protect your important data—if one drive fails, replace it with an identical drive and the data will automatically rebuild. Leave it in RAID 1 for automatic background rebuilding and optimum security for your files, or reconfigure to RAID 0 for increased data reading and writing speeds. The CADA-C32 is ideal for saving and protecting files, video, music and photographs, works great with Apple Time Machine and delivers high-capacity performance with redundant data security. The unit is factory pre-formatted in RAID 1 mode and ready to use out of the box; just plug it into your USB or FireWire 400/800 port to start securing your important files!
