Ruibling Raid

[joek71]

Hi guys, my raid crashed and I am trying to rebuild it, I have KG7-R
using the newest high point raid, when I build my raid. I have 2 maxtor 30gig drives, I partition them 4 ways, when I try to put a fat32 on it and when I load my win98 it always load into virtual drive E, I need it to load into virtual drive G: Can someplease help out.

Thanks,

Hi Joek71,

As i can see a post from you on AMD Motherboards & CPUs forum, probably you already fixed it, anyway if not, it seems you did a mistake when doing a partition on your disks(Primary and logical disks).Are you sure about that?
Let me know Joek71!

yes i fixed, totally rebuild the raid and everything else. but i have another question when I was building my raid it has an option of how much space i would like to give my raid, i selected 64k it has all the way upto 2m, what does this mean?

Hi Joek71,

Raid0 is a technique that use a method called striping.Striping is done in blocks.Those numbers that you are talking about, we call it as block size, chunk size, stripe length or stripe size.Those numbers have an impact upon performance.Data access to a hard disk involves two discrete steps: first, getting the heads of the hard disk to exactly where the data is located, which we call it as positioning; and second, transporting the data to or from the hard disk platters, which we call it as transfer.Decreasing stripe size, the files are broken into smaller and smaller pieces. This theoretically increasing transfer performance, but decreasing positioning performance.Increasing stripe size, does the opposite of decreasing it, of course, so transfer performance decreases,but improve positioning performance.There is no "optimal stripe size" for everyone; it depends on your performance needs, and the types of applications you run.As you can see, it is impossible to tell you what is the best number.That's why controller manufacturers reserve it as a user-definable value.You have to try yourself.What i can tell you is that numbers stay around between 16K and 64K(for your raid controller, of course).You can use to start, this simple idea: if you are working most of your time with audio/video edition, choose 64K.If you need to balance this numbers, or in other words, working with text files, internet, chat, games.... stay with 16K.Well, this is a simplistic way, but works most of the time.

What about 128k,256k,512k,1m and 2m what are thos used for? Mine I think is set at 64k, I think when I first created the raid i set it to 512k and my sisoft sandra raid test was slow. Can I change those settings any time without rebuibling a new raid?

Thaks,
Joe
