    Don't use an inverter. It introduces noise. Use a DC-DC intelligent power supply and get auto-start capability.
    this actually surprises me a bit... You would think that 2.5" drives (which are primarily in laptops) would withstand a mobile environment better than one designed to sit in a stationary desktop...

    That really surprised me as well, i was thinking that 2.5" drives were the most robust but i guess i was wrong.

    in my opinion 2.5 drives are better, in shock and heat and cold..
    though 3.5 drives r okay but not in extreme weather.
    just don't get a 2.5 drive with a shock protection..those drives will stop working in each and every bump on the road in order to protect the drive..

    what about just using a 16GB flash drive for booting off of and a 32GB sdhc card for storage.

    i tried a 2.5 drive..it was OK but i wanted more storage and those back then were expensive..
    i tried a 3.5 drive...it was ok but had extreme weather problems
    now i use a 2.5 drive 320 GB it is cheap and reliable and is the best i tried so far

    what i wanted to do actually was get a ssd (like 32-64 GB) for boot then use a 3.5 or a 2.5 for storage...but SSD is still very expensive
    this is my advice

    maybe for regular 2.5" drives but not for the shock version (goes by different names) of a 2.5" drive. They have accelerometers that automatically protect the drive when you hit a bump.

    memory cards have very slow transfer rates-- meaning that even a ide hdd will be faster..

    for the hdd size's:

    bugbyte didn't back up the claim with any data...
    (it has been discussed to death in other areas though)

    'in theory,' a 2.5 drive's platters will move less then a 3.5" platters, which gives 2.5" drives a potential chance for less damage due to platter fluctuation..

    2.5 drives also have less mass then a comparable 3.5--both moving, and stationary mass-- so again, in theory, they 'should' be less susceptible to vibration..

    but all this hdd talk is not very useful.

    the best hdd solution is to mount the drive solidly to the case. period. no matter if it is a 3.5, or a 2.5..

    the best solution is solid-state drive (SSD)...

    excellent info on this thread!... i actually have a question about LCD screens... is it worth i to get a motherboard for a car pc that has dvi out instead of vga if i have a lcd screen that does only vga? i would have to put a dvi-> vga adapter to plug into the screen... will the quality be any better really?

    and i read a few times on this site saying that vga loose quality and add ghosting when they get over a certain length. is that true and if so what is the length limit usually?

    no improvement in my opinion.. i would get whatever i find, if your lcd only has vga, then both ways are OK.. but think about the future.. maybe your future lcd will have dvi or hdmi..
