    How HARD are hard drives - will be mounting in race car.

    Hi
    Havent been doing much on the mp3 player front lately, however have a new project now, which is related and should be pretty interesting.
    I wont go into full details but it will be a three video camera recording system for a race car (206 gti for 2004 season) , probably running off a computer (Epia based)

    I want to know how you guys think a HD will shape up in a car. Especially one being driven around a tarmac racetrack at 100mph+ speeds.

    MAybe a special elasticated mounting system is in order. Would rather not use a laptop HD as they are megabucks for the sapce. I can get an 80gb normall HD for 55.

    Any opinions much appreciated
    Also if you have any other ideas - i need a system to record file on the fly reliably. Network is not an option at the current time i dont think.

    Cheers

    Yes.
    This is not F1 where they have 20k to blow on cameras.
    The car and support vehicles are costing enough as it is, so this is going to be done properly but economically.

    Why pay double for laptop, when 3.5 may suffice? And are quicker etc.

    Anyway, thankd for the comments, i agree a housing is probably neccersary!

    Nice to see carputer being used as race cars diagnostic.

    You can try one of those suspension system as found in model cars. I mean big proper race car 1/8 or 1/4 scale even as I think its better to suspend the whole unit rather than just the HHD. It comes with different shape, sizes, rating...you can buy the spring and dampers for it.
    Have a play around with it, Im sure you come up with an idea

    Are you gonna record the throttle, braking and speed too? How about g's being pulled on all directions?...im working on my one now.

    What sort of cam you be using? I good webcam perhaps? not sure if you can record 3 at the same time though.

    Its gonna be expensive if not a webcam as you will need video capture card too.

    I wouldn't worry about it. I have my 80gig Western Digital (and we all know how much those blow up) velcroed directly to the MDF I made my enclosure out of. I driver 100 miles per day averaging ~75mph on Pennsylvania roads. I have a stiff suspension on my car too (Koni Yellows and GC coilovers). I hit potholes and expansion joints all day while playing Divx movies and nothing bad has happened so far (about 2 weeks)

    But thats still a road car driven normally.

    A proper race car going around track do take alot of abuse...its very common to break something in a race.

    Its more of the vibrations thats gonna make things fail...HDD cable with no retaining clips...etc they can pop out. I once broke my wrist watch just by driving a gokart on a very smooth track...LOL must be a cheap one

    My suggestion would be to use a laptop hard drive. I know you are trying to keep costs down, but the smaller drives are built to withstand higher g's. I think it would be worth the extra money to be safe. Have a look around, you may be able to get a second hand drive for cheaper.
    Never let the truth get in the way of a good story

    I helped my old roommate build his car computer in his 4x4 and we had no suspension for the hard drive.

    Aside from normal driving, we also went on a few off road trips and used the computer the entire time. In nevada, we spent 4 days driving at high speeds on dirt roads. I would imagine the abuse we put on the hard drive is about what you will get racing.

    You have to keep in mind that drives are built pretty tough, and the read/write heads are extremely light aluminum. They can take quite a beating before they fail.
