I think his question was more along the line of inquiry as to what would be
the specific enclosure one would want to use. IE: what is everyone else using and the pro's & con's in our experience with the enclosures.
I am using Onnto's DataTale 4-bay RCM4DJ RAID and the TDM11H 3.5" enclosure. The RAID supports disk roaming and multiple task functions. Onnto come up with the design of the SmartGuider which I think is quite user friendly to install, insert and retrieve the disks between the RAID and the enclosure. It's a pretty cool design. Both products are USB+eSATA so for me I use eSATA to transfer music and movie files to save time. Personally I swap the disks pretty often since I need to take the disks around for work purpose. I like the convenience and user friendly design of Onnto's products. Hope this info helps. cheers.
