I'd be interested in the difference in power consumption between a 4gig 2.5" v's 3.5. These things are generally on 24x7x365 so if these is a significant reduction in power consumption per gb then these would be worth considering over the larger for factor

Sound like a great little device. Regarding the noise levels. Is it quiet enough to keep in the living room?

Like BogBeast says, power consumptions (with comparisons) would be useful in a review like this. Likewise: + noise + full-up cost with discs installed - you flirt with all these topics, but without consumating!

I'd be interested to see what the reviewer has to say about high idle temps. According to the forums and amazon reviews a lot of users are reported really unacceptably high idle temperatures. Here's an example: Still, it's the idling unit temperatures that have been causing users issues (check Synology forums). Synology replies with temperature specs that are incredible. "76C is normal because 105C is the max, and the unit shuts down at 95C" (paraphrasing). In other words 167F is ok, because Synology doesn't consider it an issue until 203F! To be clear, this is when the unit is Hibernating. Once everything is up and running, the unit cools down considerably. This is so even when all four drives are pushed to the max. The reason is the fan does not spin while the unit hibernates and the CPU, which does NOT throttle down, sits scant millimeters away from drive four.

Wow! That is going to be a safety hazard, you could cook an egg on it, keep your tea scalding hot, take the skin off your hands, or even ignite combustible material (like books) nearby. The power consumption can't be too clever either - and that is at hibernation (makes a mockery of that word's etymology, perhaps they meant aestivation?) And if the situation is only ameliorated by the running of the fans during 'normal' operation then the power consumption can only be higher still, and the noise must be quite impressive too. Can this be real?

Since the quoted power consumption for this unit is only 9.6W idle and 16.8W with disk access it would be hard to achieve such high temperatures! Reading the forms some issues may come from the way the temperature is measured via the silicone die. If such high temperatures were a problem then many users would be having lots of reliability issues which do not seem to be reported. But I would agree all reviews for devices such as this should give a indication of the units temperature during testing.

I didn't notice any overly high idle temperatures, but we only have the device for the time it takes to review the product - over time it may be a different story. Our sample was quiet and cool.

As a base unit the NAS is extremely quiet, but it will depend on which 2.5in drives you choose. All are typically much quieter than 3.5in drives, but with 4 of them running together you do need to be make sure you are picking drives that are specified to have low db under load.

2.5in drives have far lower power consumption than 3.5in drives and when 4 drives are used this is only multiplied when compared to 4 3.5in drives. As for individual figures, that would depend on the specific drive models you choose.
