-30C isn't enough, here in Montreal we get extreme weathers below that temperature in the winter, not everyday but maybe 3 times during the entire winter. I hope the HDD would prevent itself from working under unbearable temps because it won't make it in a lot of cold places Canada.

In Edmonton we can regularly hit -45C for a week at a time in the winter. (queue all the "Canada is always cold" jokes)

Feel free to send your cold air down here. It's in the 80s here (it was in the 70s but Mexico sent its hot air up here...illegally) and it is technically autumn :(

Only a 320 GB maximum size? That's not impressive; it ain't 2005 any longer.

A SSD made of slightly-sterner-than-stock stuff would be the superior option all around (as has already been said).

HDDs require a certain amount of air to work (unless this one somehow does not). Do SSDs?

While I agree that an SSD would be a better option, why do you need more than 320GB in your car? It's not like you're storing huge collections of movies and TV shows on it. It'd hold the OS for the infotainment system, maps and navigation, and space to hold music. Hell, I have a 500GB HDD in my car, and out of it, only about 75GB is used with music, and even then, that's enough music to last me a couple of months. I don't spend that much time in my car.

supply-side economics at its finest.

How is this an example of supply-side economics?

some kind of low-end industrial SSD would be much better for this application

That's the one thing I truly hate about the automotive industry. They're way freaking behind the curve, when it comes to technology not related to automotive needs. It took some of these numb nuts to realize that tape cassettes were no longer viable 4 years after the fact...

John, too expensive for this application, and not necessary.

One request, Hitachi/WD - please put in a decent sized buffer - I have had cases where the music stops because you hit a big bump, but if you cache 10 seconds worth of music (or whatever), you should be all set.

Two decades of wasted effort. Use an SSD, folks!

I was thinking the same thing. Prices are good, performance is great and durability can't be beat.

This drive is made for harsher environments than SSDs run at.

Example:
Samsung 840 Evo
Temperature 32°F to 158°F (Operating)
Vibration Operating: Random: 2.17Grms (7~800Hz)

HGST Endurastar J4K320
Temperature -22°F to 185°F (Operating)
Vibration Operating: Random: Up to 3G (10-500Hz)

While the Evos can survive in a larger range of vibration compared to J4K320s, the J4K320s can run in a greater temp range.
