Over at ProPhoto Coalition I have posted an article dealing with my latest Drobo problems and why I have come to the end of the road with these products.  Repeated hardware and software issues have left me with no reason to continue using them.  If you own a Drobo , or if you have considered owning one then I would encourage you to head on over and take a read though the article.  I take no satisfaction in writing this, Drobo have been a great company to deal with and have exceptional customer support but they just don’t have a reliable product to back it up with.
