The software is good and allows you to change between the various RAID settings. The default is RAID 0 and while this might be good for those who have a great deal of data to save, if either drive fails in this situation you lose everything. It’s likely that the majority will want to set up their array in RAID 1 format, which will split it into two 3TB drives that mirror each other. While this halves the storage potential, if one drive fails you will keep all of your data.
All in all, though, this is a solid device, with a huge amount of storage at an affordable cost. If you’re after a simple storage solution with plenty of space, this is a great option.
