DupliDisk3 Management Utility
Users who wish to maximize comfort and want automatic drive malfunction alerts must install the DupliDisk software. This utility offers a plethora of features, such as the choice of mirroring or striping RAID modes or what to do in case of a drive failure.
DupliDisk Vs. Windows Software RAID
The only real alternative to the DupliDisk would be the "classical" approach: taking two drives and a controller, creating an RAID-1 array and then installing Windows using the drivers for the controller. Alternatively, one could make do with a software RAID-1. Nonetheless, when data security is the primary concern, then this is the cheapest solution after the DupliDisk.
To create a mirrored RAID array, the two target drives must first be turned into "dynamic drives" in the Windows drive management console.
