160572	2003-07-17 10:20:00	Hi all, If I was to buy a mobo that had a chipset that supported ... say, RAID 0/1, what would I need to setup my drives in a RAID configuration? Lets also say the drives in question are ATA 133. * Am I able to have two drives that have different capacities? * Do I need totally different drives specially designed for RAID? * What kind of cabling would I need? * Are the connectors on the mobo for RAID the same as IDE connectors? I mean the thing that the end of the cable goes into on the mobo. * Would I need to use an O/S that supports RAID? * Using RAID, what would that do to the capacity of the two drives? *Have i left anything out? Thanks - aNtz	aNtz (4238)

It is best to use the same type of hard drive (speed, size, etc) when configuring RAID. If you set up a RAID 0 or striping array you won't lose any (or negligible) hard drive space. A mirrored array obviously will only give you half the number of Gb available. Striping is useful for speeding access and write speeds so is good for video editing or file server applications while mirroring is obviously good for saving data to. The problem with striping is that often if one drive dies you lose all of your data. When a mirrored drive dies you can replace it and then the data is copied onto it from the surviving drive. Mirroring can slow write access times down as the drives use integrity checking of the data. Most RAID "cards" come with set-up software and are usually independent of the O/s.	Gorela (901)
