thank you... :-P
which would mean you would have to go even faster than that. So I should ammend it to "hit a brick wall at a minimum speed of 7672.7mph"

Yup hard drives are more durable than you or the car....
Well my hdd died. I am looking at getting a SSD now as their prices are no longer ridiculous.
Sometimes you get a short life drive.... do not blame the car automatically.
an undetected fault when the drive was built.
possible but rare poor install/mount and motion related.
Really one of my drives survived 3 car wrecks while in use, two of the cars did not. They are generally very durable. I do not recommend testing this personally.
Well... the 350G is non-operational shock for a 3.5" HDD. Operational shock tolerance is much less. It is around 68G. Not a small number anyways.
Basically 2.5" drives are much much more resilient to shock and vibes...Typical specs as below.
2.5" HDD: 350 g @ 2ms (operating) / 900 g @ 1ms (non-operating)
3.5" HDD: 68 g @ 2ms (operating) / 350 g @ 1ms (non-operating)
I work for a company specialised in Automotive, Locomotive, Aeronautic Digital Video Equipments with some of the products having 2.5" and 3.5" HDD's for video storage. We have technical tie-up with major HDD manufacturers and we have discussed this shock and vibration issue in length with them for size and cost optimisation
End Result: All our products employing 2.5" as well as 3.5" HDD's are shock mounted with wire-rope isolators. This is essential for us to meet our product MTBF numbers of 125,000 hrs.
Carputer use: If you can afford some sort of shock mounting for the HDD, it always benefits.
But according to our vibration tests, modern drives can reliably withstand most of the shock and vibes a car sees in a day to day use even without any shock mounting but the HDD reliability will be reduced to say...5 yrs or so...With HDD prices at the current low levels, do you even care?
drives are quite durable under not too cold conditions, but when it goes pretty cold they're reliability goes way down. My drives survives basically 1 winter each time, then usually by springs i have to replace it with a new one. Considering SSD soon since its only down to 150/32gb now.
Pardon me but this does not match our collective experiance.
Several members report well over 5 years of use and I would encourage you to carefully define what you mean by shock mounting.
Because a hard mount to the vehicle has proven to be very reliable while incorrectly shock mounting can potentially (maybe even likely) make motion related failure occur.
Strange, I have also killed several regular hard drives after exposing them to the winter chill. They were free though, so oh well. But my automotive grade drive has been extremely resilient to both shock and temperature. I just bought the new Seagate ee25.2 80gb automotive grade drive, so if anyone wants my old 20gb ee25 one, send me a pm. Its still under warranty until 2011.
