Conclusion.
I was slightly worried when I first saw that the Luxon didn't have any kind of cooling, and my fears turned out to be justified on this occasion.
Heat, almost certainly affected the hard disk performance slightly, and I believe that possible damage could occur if a drive was left running inside this enclosure for long periods of time.
The other slight annoyance was the vibration that happens when the drive is spinning. There are all kinds of noises that seem to be amplified by the design of the casing. The plastic desk stand that comes with the Luxon caused a high pitched - wasp like noise at certain times when the hard drive was working hard, and had to be removed.
It wasn't all bad though. I particularly liked the long
LED disk indicator covers which were complimented nicely by the excellent black and silver taco shell design of the outer casing.
For occasional backup and a good looking storage solution, this is a decent enough enclosure, but it is let down by the overheating problem if you plan to leave it on for any length of time.
To sum up, the Luxon definitely has potential, but needs some work on the cooling.
