Review on SilverStone Technology External Swappable RL DS222 by Covey Palmer

Looks like a very good design. The subtle instructions on the installation CD but easy to understand setup of the 54x 3TB drives give me about 8.5TB of formatted space. Connects via USB 3, replaces added SCZI card in DELL Precision WS for half the cost of a new card. Runs very quietly - there is no way to disable the 5 minute idle transition to sleep that I see. Reference is made to this SOP in the manual. Now dead – just three years later. I turned it off to move the device while I was working on the computer - it didn't turn back on. I have cycled the device off and on from time to time for the past three years up to November 1st 2019 with no issues. The cheap Terra Master raid box I bought later can last longer and is mostly plastic compared to a good Silverstone unit.
