screenshot_180No one has commented on the similarity of the new Apple Time Capsule to one of those fragrant candles used to instil a sense of well-being.

I had the older type Time Capsules, but also an unfortunate track record with them, where they overheated and then expired. I lost two of them that way, before I eventually discovered it was (allegedly) a well known fault. Apparently the non-cooled power supply would get too hot, a capacitor would pop and that would be the end. For a time there was a web-site dedicated to the problem, which appeared to happen after an average if 19 months and 20 days

When it first happened at rashbre central, I took one apart to have a look, and noted the absence of ventilation. Instead of making some holes in the base, it was covered with a rubber compound, no doubt because of the internal mains supply. I still have a 2009 picture of it in the bin sans disk. The internal metal layer was perforated, but the engineers didn't have the last word on this industrial design.

It caused me to reconfigure the rashbre central backups to a separate disk system, instead of using the disks inside the units and I added a large metal heatsink (an old disk drive) to the outside of the remaining capsules to radiate away the warmth. Fortunately they were out of sight.

The interesting advantage of the newer type seems to be their increased speed. Even with the old ones, the wireless communication between them was more reliable than using a wire-based LAN connection across the mains supply (from upstairs to downstairs.

I'll try a couple as a Wifi extension to see whether I can get the higher internal speeds advertised.

I take it the Apple Time Capsule is a back-up system? I only use a Mac at work. With all kinds of electronics being known for overheating without ventilation, you'd have thought they would have sorted that out!
