hello
i have for a very long time wanting to expariment with raid setup
so i finally got a hold of a raid card and i got two 40 gig hard drives and set them up as a mirrored raid, i then loaded windows xp
but there is no increase in speed???
i have a 2.4 GHz with HT
512 DDR 400 PC3200
Intel 865
most IDE raid cards do not support simultanious reading when in mirrored mode, meaning your are getting 100% data redundancy, and no speed increase. If your looking for the "umpf" of speed increase, you will have to install in a "stripe" set (raid 0). This provides no redundancy, but WILL be faster
Like Mat said, you are running Raid 1 (mirror) when you should be running Raid 0 (Stripe)
Beware, running Raid 0 increases the speed but if one drive goes pooey, then ALL data is lost
As Mat and RD says you didn't set it up right for speed, only for security.
To be honest, there are better ways to increase speed without jeapordizing data integrity.
You can try raid 0+1, but perhaps you can tell us what you really want.
Then we can help further.

Yes but doesn't raid 0+1 require twice as many drives as raid 0 or 1? Thought so.

RAID 0 1 (0+1) is striping (RAID 0) and mirroring (RAID 1) combined, without parity (redundancy data) having to be calculated and written. The advantage of RAID 0 1 is fast data access (like RAID 0), but with the ability to lose one drive and have a complete duplicate surviving drive or set of drives (like RAID 1)

What would YOU recommend????
Albeit much slower and taking more HDD space.....Quote:

So, we are left to wonder what it is that ngc has in mind.
Is it speed or security?
Or both????
why don't we stop the bikering and let the orignal author reply with more details?Quote:

So, if you wll, let us help him, not confuse him: the reason I askied what he was trying to accomplish.https://forums.windrivers.com/images.../2007/09/1.gif
you can confuse just as easily by providing too much information as much as not providing enough.Quote:

Wasn't trying to bicker just was pointing out an obvious oversite. The person said they only had 2 drives and one of the options mentioned requires more than 2 drives so I pointed that out.
