    i wanted to know if my 3gb of pc5300 ram is slowing down my sata Hd...im only getting 70MB of read speeds. Would it make a difference if i got pc6400 ram?

    Ram is much faster than a hard drive.

    Old pc66 sdram was still measured in nano-seconds. So your memory is not your bottleneck.

    Is this Vista? It has issues with read/write.

    The only way RAM and HDDs conflict with each other is if you don't have enough RAM, the HDD with the virtual memory file on it will appear to slow down because the virtual memory file is getting used constantly. It's pretty obvious when this is happening, though; it won't just have a slight effect.

    Vista is good at basic things like constant security pop-ups, but bad at complicated high tech things like reading and writing to disk. The technology just isn't there yet to handle such bleeding edge operations.

    70 MB/s is about right for a single desktop drive

    70mb read/write is a fairly normal speed regardless of OS. Stop cockriding Apple at every pathetic and unrelated event.

    SATA-2 has a maximum of 3Gb/s. However, no drive currently in production can come close to that. Hell, the only drives that could even max out ATA-6 are the best SCSI drives on the planet, though obviously they wouldn't work because they're SCSI, not ATA.

    SATA-2 has such a high capacity for two reasons: one, it makes the standard futureproof for probably at least a decade; and two, big numbers sell units. It's kinda like ZFS for Solaris; it's designed to be so expandable that a computer that could max it out would use so much energy it would boil all the water in the world all at once, but that way you know it won't ever be inadequate.

    Actually, I was cockriding XP you dolt. You know... you only have one metaphor, and its male anal penetration. Are you openly gay, or do you hide it?

    300MB/s is ridiculously-fast transfer speed for a desktop computer. It's also impossible to achieve using a single disk at this point in time.

    well that is not what my mother board specs say or hard drive. both are Sata 2 which is 300mbs.

    What is next? my 2.6ghz CPU does not actually run at 2.6? Only runs half of that? Seriously, You people should go over to the Anandtech Forums, many more knowledgeable people in the computer forums.

    You are totally full of shit, you know that? The limiting factor on ALL hard drives is the inertia of the moving parts. There is only so fast that little reader arm can swing back and forth, and there's only so fast that the platters can spin without flinging their lubricant off (15krpm is the limit right now), and so there is only so fast that the mechanical parts of the drive can deliver the data requested by the user.

    The best 7200rpm drive, even with command queueing to allow data requests to be fulfilled in the most efficient order, can still only transfer data at about 100Mb/s tops because of the combination of bit density, spindle RPM, and the inertia of the reader arm.

    Similar to Cd-rs? The max speed will aways be 52x, anything higher and the disc will break?
