    Does SATA 3G offer any noticeable performance upgrade? Is the technology fully utilized on the software level?

    No, there's a very slight difference, and that's about it. The hard drives spindle speed is the true measure of how fast it will read/write data

    There is no existing hard drive capable of sustaining a 3 gigabyte-per-second data transfer.

    Oh alright.. so that's the bottleneck variable. Thanks :wiggle:

    I'm curious what the 10k raptor utilizes of that 3gb/s bandwidth

    The last I heard, they burst at maybe 60MB/sec. Whatever it is, it isn't even remotely close to the interface maximum.

    I've actually seen sustained data transfer rates of 150mb/s (bursted higher) over SATAII. These were Seagate drives with NCQ technology, and a high-end RAID card.

    really soon im just going to purchase 1 WD 74gb raptor and just use another slower hardrive for data saving, that way gamming and loading of programs on the main hardrive should be plenty fast. I heard this is the best way to go about it in terms of hardrive performance.

    I bought three of those and RAIDed them together. They work nicely. Even with a PCI slot bottlenecking the data transfer, my hard drive subsystem scored 40% more PCMarks than my old IDE drive.

    Just think what you could do with a PCIe card for those drives. :noes:

    Or an onboard controller. Yep, it would be nice if I were in the mood to spend money on my computer. Alas, since I've maxxed out my Athlon XP platform, I'm instead spending thousands of dollars on modding my VW Passat.

    (and by "modding", I mean "fixing the stuff the prior owners allowed to break, so I can have a car that works right".)
