hi, I bought a DroboFS about a week ago after I did only about a weeks worth of research, I was sold on it. Reviews were great and it seemed so Mac friendly. I'm not disapointed at all. Its great. OK its large but has 5 bays and dual disk redundancy if needed, so enough to expand and double protection. I only got 3 x 3TB drives as they are pricy at the moment. I wanted a server hidden away in a cupboard in the house, and for it to my Personal work, some freelance work and, photos, itunes media and also Time Machine back ups for three mac's.
After I got it I came across a review online with some critisiums about it, but I think these were the older versions of the Drobo and the photograher who did the review had used Drobos for 2 years with only one failure. He now has updated to Promise drive , which is mega money.
Hopefully it wil work ok with my Apple TV as I have a dedicated itunesMedia volume on it, so any mac can add files to it and it. I dont think it can be accessed directly to apple TV which is a pain, and Itunes has to be in for it to stream though. I wil update how it works.
Just incase I have total failure. I have decided to also use one of my old external HDs to back up my main photos and media and take this offsite as a secureity thing just incase the DroboFS Fails, but its working great at the moment. I need to test it out alot more though.
It has a gigabit ethernet connection, and is fast. Although slow to copy all your stuff over to begin with.
At last a clear desktop with no wires to external HDs.
Sweet
.. oh and Drobo Dashboard is easy to use and is working fine on Lion. I think they had issues, but worked it out now.
