Performance
We equipped Drobo with four different hard drives (80 GB, 160 GB, 320 GB, and 400 GB) for our test with HD Tach (version 3.0.1.0). We received average sequential transfer rates of 15.7 MB/s (read) and 11.0 MB/s (write). Compared to other USB storage devices, Drobo doesn't convince with high performance. However, most external hard drives don't come with data security features like Drobo does. The average access time was 27.7 ms, which puts our data robot on an NAS-device level. In practice, this means that users need a lot of time if they want to store 500 GB on Drobo. We still think that Drobo's performance is acceptable after all. Different software, which is easy to install for users, is supposed to provide a performance increase, according to Data Robotics.

Thank you for your review. I only want to add that there is a 2nd generation drobo that gives Firewire support. Also, you can buy droboshare to go along with one or two drobo for network access. I would be most interested in reading your thoughts about the different connection abilities and speeds. http://www.drobo.com/Products/Index.html
Thanks again
