terrible write performance when almost full

well, obviously it wouldn't generate any more heat than a fridge in your kitchen generates...

Actually, your wrong. The kitchen fridge is actually "working" only a few % of the day. A fridge with a heat source in would be working a LOT. Even if it's a small heatsourse. And these NAS'es arent THAT small. We are talking an easy 100w. I wouldn't be shocked if the fridge compressor would be working pretty much 24/7.
B!

good point! I guess I will have to try it out and see if a normal fridge could even keep up with device generated heat

There are some quite small mini dehumidifier systems that you re-charge by plugging them in. http://www.amazon.com/Remington-Model-3 ... B0028M3YU6 Many are targeted at gun owners.

So that is potentially an option. The models I saw are too large to fit in a drive tray, but they are possibly useful if the NAS is in a small cabinet.

BTW, typical power use for an NV+ v2 is about 50 watts per http://www.netgear.com/images/ReadyNAS_ ... -57079.pdf. So your 100 watt number seems high. Are you seeing a larger power draw?

Well, first of i got the NV+ V1, so my numbers arent exactly representative, but i did see an easy 100w when putting it under load, until i replaced the drives with 4 Seagate ST2000VX002-1AH166. The older drives were just 500GB drives i had laying around, Seagate / WD, and not exactly the most "green" drives i could find. With the current drives maxing out at 7w a pop it seams heat dropped somewhat, and wattmeter seams to confirm this. Trying to load it down with both running torrents, and grabbing transfers it seams to peak at 90-95w. Far from typical load, i think they list 55w as being typical for the v1's. But then again, typical load isn't interesting when your trying to work out your cooling solutions, you have to handle full load, and simply let the cooling not work as hard when your at less.

Either way, i think it's hard to measure the energy generated by decaying food matters in a fridge, so even at the "typical power use" of 50w your well past normal fridge loads. Depending on your usage pattern, and the fridge used, your going to end up real close to what it can effectively handle, and the compressors in these things aren't made for continual use. The lubricant breaks down when the compressor heats up, and if your unlucky, a couple of days continual running is enough to make it metal scraps ready for recycling.

I'm not suggesting that you should use a fridge. Even if it were practical in a normal home environment, it clearly doesn't make sense on a boat.

The mini-dehumidifier looks possible, since it is designed to go into enclosed (but not airtight) spaces.

Well, having pretty accurate energy monitors on the boat, our small 6 cubic foot fridge with 1.5 cubic foot freezer, with good insulation for the tropics uses about 6A at 12V when running, and has a 35-50% duty cycle depending on the temp of the air and water. That works out around 864 Watt/Hours a day.

My NV+ v2 with 4x 2Tb Spinpoints in it uses around 3.7 A at 12V, so the ~50watts rating netgear shows is pretty correct. It does spike up to around 5-6A during spinup though, and I am not running anything in the background on the unit, just the file share service. That does in include the inverter overhead, which is quite small in the case of what I am using. I have meant to build a 12V-12V switching supply so I can run it straight off the bateries, just havn't gotten to that yet...

this is an ext3/ext4 problem going back a few years, not really readynas specific. you can google ext4 fragmentation for lots of info

Utter rubbish.

The box simply does not do what it should be doing - you've got a bug in your firmware.
