    5400 or 7200 rpm harddrive..

    would drive speed make a difference in a carputer? like the system im building is for a jetway amd set up with a 1.4 GHZ processor with a 80GB 2.5 5400rmp sata drive...would getting a 7200 make a big difference? i mean..all i need it for music/video...the usual carpc stuff...its not like im going to do photoshop on it or play crisis on it...... music -video -dvd - visualizations..that it..not much more...

    No, a 7200 rpm won't make a difference. I went from a 7200rpm IDE 60GB to a 5400rpm SATA 120GB drive and didn't notice a thing. Carpc aren't that demanding.

    in theory boot times and disk access will be faster with a 7200RPM

    BUT

    the faster it spins the more chance there is of a bump in the road making a bump on your disk, and more chance of losing data

    5400rpm sata is heaps fast enough for a car anyway.

    5400 rpm hybrid (readydrive). Idle most of the time.
    My opinion is my own.

    the higher RPM disk has higher inertia (i dont know, if its the proper expression), so its more secure in theory... but it depends on many thing, like its rotation/position, and others... so, i have a 7200 disc because its faster than 5400...

    The hybrid readydrive uses a flash disk in conjuction with the harddrive, writing what is needed to the flash, then stopping the heads. So the 5400 rpm really doesn't mean anything.
    My opinion is my own.

    there is no disk in flash memory.

    And the 5400 means alot when booting.

    Only time you will ever notice the difference is at a full boot, and during file transfers. Other times your disk is at like 1% average usage.

    Built in Flash DRIVE....happy now?
    Actually, watching the harddrive light, it is a LOT different from a non-hybrid drive on activity.
    My opinion is my own.

    I meant the only difference statement on non-hybrid drives. Probably should have had some sort of transitional sentence in their too. Oh well. But yes the difference between a flash based hybrid drive and a good 'ol 100% magnetic disk are quite large. Also big differences in power consumption (if your OS supports it).

    If you visit tom's hardware you can view a list of 2.5" hard drives with their read/write performance numbers, in there you'll be surprised some 5400 rpms are faster at delivering data than 7200 rpms. With hibernate cutting down boot times to mere seconds there really isn't a need for fast drives on a carpc.
