I used the free personal raidrive and it’s quite good.
However, trying the pro product is an entirely different experience.
What can I say, when I pay money (or intend to) I expect some level of support, starting with top-notch documentation and having a support address for pro users or a forum much more lively and full of information.
None of the above exists as of yet.
It seems that the product is too new or to “freebie” yet to be a professional business product.
