Help teach me about RAID

post #1 of 35
Thread Starter 
Ok, I'm new to RAID. I want to know if I can get a performance increase using any sort of RAID. And i know you have to use a certain number of hard drives to configure RAID, and was wondering could I just partition lets say a 1TB drive, and just do RAID inside that. I would also like to learn more about other RAID options

You need a minimum of two identical hard drives. You'll see the biggest performance increase by using raid 0. It essentially uses the 2 drives as one big drive but writes on both simultaneously, thus increasing the speed. You'll need to format both drives and install the raid drivers during the windows installation.

Raid is redundant array of inexpensive disks.
Raid 0: files are split across multiple drives for speed
raid 1: drives are mirrored for security
There are many other raid arrays that can be more complex
many mobos have raid controlers for certain arrays but the best perforamance is from a dedicated

There is a good wiki article: http://en.wikipedia.org/wiki/RAID

If that was a question, then your answer is yes.

No they do not. They have to be the same make/model...but not the same size. Making a raid array from 2 different size drives will result in an array equal to 2x the smaller of the 2 drives.

I should have specified, rep+ for adding that.

I was referring to RAID -0-, as far as I knew they had to be the same size, no?
