S-ATA RAID 0 Performance

Archived from groups: microsoft.public.windowsxp.hardware (More info?)

Ok, I'm seeing all this stuff on SATA, and all this stuff
on the improvement in performance of a SATA RAID array. I
did some research.

Basically, every company that does a benchmark is coming
up with different results for performance.

I want some people that actually have a S-ATA RAID 0
array to tell me how things run before I make the
investment.

Such as, stripe size. I read that faster I/O comes from a
smaller stripe size, but better performance for games and
stuff with a 128. Has anybody tried multiple sizes and
are able to tell me what they feel the difference is?

All you see is smaller = speed, larger = performance. I
want some real actual details of how much performance and
speed you get.

Also, Pagefile performance. If you have heavy pagefile
usage, does S-ATA RAID 0 boost performance of this? I
would imagine things are considerably faster with this.
Just need some feedback for verification.

I'm just hesitant to sink the money into this. It seems
like it's a boost, but exactly how much of a boost? From
what I've read, the best drive for a gamer like me is the
74 gig 10k RPM S-ATA Raptor. From what I've read, this
drive will outperform the 36 gig WD Raptor?

2 of the 74 gig drives are definately expensive. I just
want to make sure they are worth the money.

So, hit me with some feedback. Assuming I get some good
responses I'd like to get the drives purchased ASAP.

Thank you in advance

    While I do not have the data you seek on SATA (my SATA drives are not
    striped together), I can offer these observations:

    1. My disk-to-disk transfer rate is about 3X faster with SATA/150 than with
    ATA/100. The ATA/100 drives are on the same controller as master and slave,
    so they perform at a "50" speed when talking to each other. In contrast,
    the SATA/150 drives are each on their own controller, so they can both do
    the "150" speed simultaneously

    2. Instead of think about any disk as a way of making the pagefile faster,
    think about more RAM. Even the cheapest RAM suitable for modern computers
    is far faster than an disk. In fact, you might want to set the pagefile to
    zero if you have have at least 1Gig of RAM.

    3. You might have better luck obtaining the advice you seek in other forums,
    which are dedicated to games or custom PCs. Try a web search on
    "overclocking", "games", etc.

    Good luck in your quest for the perfect gaming system.
