Addendum:
The LaCie 2big Triple was a great RAID unit, but too noisy for the desktop, fan runs continuously, 'Auto' switch did nothing (wouldn't sleep), and the one-push-button on the front is 2big and 2bright. It was well built though. Heavy [duty] metal enclosure and drive trays. It's hard finding the perfect solution (4 drives; 2 for RAID 1 / 2 for JBOD separate access).
Looking at CalDigit VR instead. More $$ but more features/expandable/upgradable.
