How much faster are SATA hard drives in comparison with their IDE counterparts?

Posted on October 26, 2009 by admin

I have got a new 160gb SATA hard drive to which i will be backing up some files. I was wondering how much faster they are in comparison to my current IDE hard drives.

SATA is newer technology than IDE, and generally SATA drives are going to perform better than their IDE counterparts.
It is much faster than IDE

    Generally a lot faster.

    SATA is 4 times faster than IDE

    SATA or SATA !!? it depends on your SATA port on your computer, but generally, Serial ATA drives are 9 times faster even though they spin at 7200 rpm (the data transfer on SATA ports is 9 times faster than IDE/Parallel sometimes called PATA)

    SATA hard drives are 300mph faster than IDE hard drives depending on what car you driving. I have a Bugatti Veyron and I have a 600mph SATA hard drive.

    Not much.

    I must stress that I am a hardware student and we have studied the standards in class ( so you know I know what I am talking about ).

    The best of the IDE-s ( the IDE133 ) had an 146 Mb/s transfer rate at 7200 rpm.
    The SATA-1 has an 150 Mb/s transfer rate at 7200 rpm.

    What is essential for a HDD speed is _not_ the standard, but the speed at which it rotates. For example, a 10.000 rpm hard drive would be A LOT faster than a 7.200 rpm hard drive, regardless of their standards.

    SATA provides smaller cables, bigger buffers, and a better protocol ( regarding safety, security and eror-resistence ). But that’s all. Its spead increases come only from the fact that the protocol itself introduces less overhead on the data transmited. The rate of transmission errors ( where the data needs to be re-transmitted ) is smaller, and the stream of data is less encumbered by the protocol.

    Summary :

    Not much, but SATA is prefferable as a standard because of the small cables. IDE is obsolete and should not be used.

    Best of luck!
