The new Freecom DataTank is the ideal platform to store all your valuable data on. The easy to use configuration tool allows you to choose between RAID 0 striping, combines the capacity of both disks into one volume; you will see the total capacity as one driveletter in your operating system, RAID 1 mirroring, one disk copies the other automatically, so you always have a safe copy of your data; you will see one driveletter in your operating system for half of the total drive capacity or JBOD dual drive letter, both disks will appear as separate drive letters in your operating system. Large storage capacity is one thing, but what about security?
