Ata Speeds - Many Questions....

Discussion in 'General Hardware' started by Dreaded Lurgee, Jul 22, 2003.

  1. Help!

    I've built myself a nice cheap little system :-

    MSI 6339 i850 Pro board
    P4 (skt423) 1.7
    2 x 256 PC800 Rambus
    1x Maxtor AT133 60gig (6Y060L0)
    1x Wester Digital ATA100 80gig (WDC WD800BB-00DKA0)
    1x MSI 8348 43x16x48 CD/RW
    1x ARTEC 16X DVD Rom
    Silicon Image SiI 680 Ultra-133 RAID Controller
    XP Pro (SP1)

    I have them set up as follows at present - Maxtor on the SiI's Primary channel, WD on the SiI's secondary, CD/RW on the motherboards primary and the DVD on the secondary. And I'm using ATA133 rated cables.

    The HD's are set up as standard IDE (will use the RAID functionality when I can afford more drives)

    The problem seems to be the transfer speeds. I was under the impression that ATA133 meant (up to)133MB/s. Is this wrong as HDTach says that the max transfer rate for the Maxtor is 49611kps(average 39800kps) and the WD is 58157kps (average 48000kps). I've copied/pasted the info on the drives given by the SiICFg utility that came with the card below (makes no sense to me).

    Should my drives not be quicker than this???
    How do I make them quicker?
    Also, why do the drives capacities not match what they should be (Maxtor is 58644MB, WD is 76319MB) ROBBED! :confused:
    And my CD/DVD drives don't seem to sharp neither....

    Thanks
    DL.

    To summarize:
    1. The interface can handle up to 133 MB/s. The drives however never reach this except during data bursts from the cache.

    2. Manufacturers count 1000 bytes = 1 kbyte.
    Windows counts 1024 bytes = 1 kbyte. The latter is the correct way due to the nature of binary numbers.
     
  4. Thanks guys.

    I must say though that I feel more than a little deceived. :mad:

    I just wish that when the time comes for my boss to review salaries, he rounds it up in a similar fasion.

    Cheers!

    Put the two har drives on the primary IDE contoller and the cdrom on the secondary controller. You should not mix cdroms with hard drives on the same controller.

    The way I have my system set up is as follows...

    Onboard Primary IDE - 40gb seagate ata100 (master)
    Onboard Secondary IDE - 16x DVDROM (master) : 48x CDRW (slave)

    RAID/ATA133 primary IDE - 80gb maxtor ata133 (master) : 30gb maxtor ata133 (slave)
    RAID/ATA133 secondary IDE - 30gb quantum ata100 (master)


    I've had problems with having the primary hdd on a ata controller card before and therefore wont do it again to avoid any similar problems as I had before. However, I wouldnt (or would try not to) mix up ata100 with ata133 on the same channel - I'm sure both drives would run at the slower speed.

    not at all. windows will show different dma speeds for each drive on that channel in device manager...

    OK OK....:p Re-read the above question.............

    /Me saw RAID and assumed it was a JBOD array he wanted. :eek:

    Even so, the drives are read/written to at different access
    speeds, although in real terms this doesn't amount to a great deal.

    In theory the transfer should be 133MB/s and 100MB/s but
    these are burst transfer speeds.

    Not many drives can transfer above 30MB/s sustained even
    though they may be >=UDMA100 drives.

    Provided the drives are of similar rotation speed (i.e.7200rpm)
    and of equal size, be it UDMA33 or UDMA133 drives, the
    performance difference is negligible.
    :D
