    Higher Capacity Hard Drives run faster?

    Lets say we have two hard drives 7200rpm that are the same in every aspect except capacity wise. One is 100gb and the other is 200gb.

    If I were to use up 60gb in each of the harddrives filled with vista, office 2007..etc. Is it correct to assume the 200bg harddrive will perform faster? if so is the speed difference that drastic?

    Personally I just ordered at Hitachi TravelStar 7K200 200gb and just wanted to know if the difference was that drastic when compared in this situation,

    Theoretically it would because if properly fragmented the head would need to move less in order to acsess data from differnt parts of the drive.
    In reality i dont think it makes a differance , And it may infact be slower as the head my have to be more precise or somthing??

    HIgher density means higher platter density which equals faster performance. It means more data is collected per movement of the head.

    There are other factors as well. If it's got perpendicular recording it can be faster. Some brands are faster than others. The Seagate Momentus 5400.3 is particularily fast for a 5400 RPM.

    If you want speed and capacity the western digital scorpio is the best one , 250gb and only a little slower than the leading drive?? But , i see it does make a big differance , The lowest 200gb is about 2/3rds of the way down the chart above alot of 5400 rpm drives and its only 4200 rpm!!! and the other 200gb one seems half way up and it is also only 4200 rpm , I guess it makes a big differance then :)

    :) How much for and what speed?And also how do you test your hard drive? I wanna see what my average read / write speeds are. Is there a software program or do i do it from a stopwatch and large file?

    Outside of disk has more data per revolution than inside. Outside larger inside smaller same # of revolutions outside is more data in same time period.
