I currently use a Dell RD1000 external USB 2.0 dock to backup my server. I am thinking about upgrading to USB 3.0 and would need a new external RDX dock.
Are all brands the same? I see that Tandberg and Imation both have USB 3.0 docks for about $150. After a quick search it seems that HP and Quantum only offer USB 2.0. The USB 3.0 Dell RD1000 is much more expensive at $630 with one 1TB drive bundled - so about $375 for the dock itself.
Also, I know how USB 3.0 is much faster in terms of transfer rates. What is the actual read/write performance difference between external RDX drives running 3.0 and 2.0? In other words, can the removable disks handle data at USB 3.0 speeds or do they spin to slow?
It would be great to hear from IT people who are actually using Tandberg or Imation docks to backup servers.
