I have been using my Drobo for about a month now and i am very pleased with it. The details within the Amazon page sum up the machine very well, and it really does what it says on the label, and is very easy to use.
I am a Mac user and the software works seamlessly with the Mac.
I am now storing all my multimedia files on the Drobo with the knowledge that it is all back up safely.
Well worth a look, and purchase!
