I've never tried Orico, that was just the first brand that came up when I searched. I suspect these things are fundamentally unreliable, especially because they are powered by external AC adaptors, meaning there is no real ground between the two switching power sources (one in your PC, the other in the HDD caddy). It's either due to that, or due to the very sensitive signaling along the line, that eventually you get USB disconnects (if you try to run it as an appliance) that wreaks havoc on filesystems, particularly RAID.

The Jonsbo N3 is not comparable. I own one as well (how quiet is yours? I upgraded the rear fan but my CPU fan is noisy), but it's a complete PC case, not an external HDD array.
