FSX/readyboost drive/performance

Discussion in 'Windows Vista Games' started by Heath P. Dillon, Dec 13, 2008.

  1. Hi,

    My understanding is that a ready boost drive is a usb drive that vista uses
    to dump data to, rather than a hard disk as the readyboost drive is
    considered to be faster than the hard disk.

    So if my comment above is true, and I can now buy a 32gb readyboost drive
    for $70, is it a good idea to install games such as FsX onto a readyboost
    drive, and get better performance than using a HDD...

    ???

    Thanks

    Readyboost is a good thing for systems with less than 1gb of memory and
    really slow hard drives, but over 1gb it doesn't seem to help much. However
    the actual issue is USB stick performance as a disk drive.

    On my system (Vista32, 2gb memory), using PerformanceTest 6.1:

    EIDE drive:
    sequential read=49.6MBytes/Sec, Seq write=53.7MBytes/Sec, Random
    r/w=3.41MBytes/Sec

    SATA drive:
    sequential read=57.7MBytes/Sec, Seq write=48.5MBytes/Sec, Random
    r/w=2.59MBytes/Sec

    USB2.0-connected external hard drive (Buffalo) I use for backups:
    sequential read=20.5MBytes/Sec, Seq write=20.3MBytes/Sec, Random
    r/w=2.91MBytes/Sec

    1gb Memorex memory stick, plugged into a USB2.0 port:
    sequential read=10.3MBytes/Sec, Seq write=0.74MBytes/Sec, Random
    r/w=0.13MBytes/Sec


    The memory stick seemed really slow so I ran the test several times with the
    same results. Now my stick is a fairly old one so newer ones may be a lot
    faster, but the point is that you would have to check and see what your
    stick gives, you may end up without any performance increase.

    Hope that helps!

  3. Firstly Readyboost only works up to 4GB in size so if you bought a 32GB usb
    stick to use for readyboost then only the first 4gb would be used by the
    system and the other 28gb would be wasted.

    Secondly Readyboost works as a temp drive to cache data the operating system
    thinks you might need, for example certain files for programs you might
    regularly open so you dont actually install programs to the readyboost usb
    drive.

    Lastly, and this is more in responce to the other posters responce about
    drive speeds, the benefit of flash storage over hard disks isnt read/write
    speeds but instant seek times for a certain piece of data. So instead of
    with your conventional hard drive having do spin the platter around to the
    right location before it can start reading, flash can instantly access any
    sector on the disk making it very quick for random reads of small pieces of
    data. For sequencial blocks of data, eg a 700mb video file hard drives are
    still the quickest storage medium as the disk only has to seek once to find
    the start of the file and is then reading a continuous stream of data as the
    disk turns.

    ReadyBoost is, as I understand it, just extra Cache RAM, and not really
    that great a thing. Like others have said it's good if you have a 1gig
    system ram, but anything over that it doesn't really help that much. The
    other problem is USB drives (HDD or Flash RAM sticks) just aren't that
    fast vs. your internal drive, so there's really no reason to install
    anything onto an external drive and expect better performance.

    Now, if you have an eSATA hard drive, that "should" be as fast or faster
    than your internal drive, so you could install an application externally
    that way, but otherwise it's important to remember that the hard drive
    inside your system is your slowest component, USB drives are slower than
    that so more system ram means you won't have to use those other slower
    components as often.

    Confused? Read a book.
