I have searched the most common sources for power consumption by the Seagate 2tb External hard drive STEA2000400.

I use this on my HooToo travel router with a 10400mah battery, but I don't know the power draw and how long it will last without recharge.

Can anyone tell me the power draw of the drive?

Also are there alternative solutions for high capacity storage? The HooToo router will accept up to 4 terabytes.

Well most HDDs have operating temperature of 0°C to 60°C so I'd say that the drive is OK at 50°C. However as you've mentioned, the cooler - the better. There's no guarantee that a drive running at 40°C most of the time will outlive one that runs at 50°C, but theoretically, it is more likely for the one that's running hotter to wear out more with time.

Anyway, good job on finding out the information you were looking for! :)

Hey there, BigXor.

You should be able to find the power requirements for the model in its technical specification sheet or user manual. If there's no such info presented there, you could get in touch with the drive manufacturer's customer support for more info.

Hope that helps.

Thanks for the reply.

Amazingly your reply came a few minutes after find the info in the most unlikely place. I exhausted search engine reviews, tech specs, etc., and was looking at the Amazon reviews for the 2TB 'Backup Drive', which is the identical drive as the 'Expansion Drive'. One review stated that he measured the operating power as .7 watt idle and 5.3 watt writing large media files.

Also the heat generated on my expansion drive runs between 46-50 Celsius (@ 24 C ambient). This heat buildup is due to a plastic unvented case. I don't want to keep this drive because the heat will cause premature failure. My experience with hard drives is not to let them operate higher than 40C.

Unbelievably Seagate does not have this information listed anywhere including on the case specs.

So I'm miffed at this because it was not possible to calculate the impact of extra power drain on a small netbook.
