Creating the First Array
Now lets turn to the RAID BIOS. Usually, youll be asked to press CTRL-I to enter the RAID BIOS on sys-tems using Intel chipsets. Were assuming here that the RAID 0 volume is to be the first array, with Windows to be installed on it. But if you want RAID 1 to be the first volume, just reverse the steps. Note that some BIOS screen shots may show a third physical drive. Well ignore that for our purposes here.
All drives start as non-RAID drives. Using the cursor and Enter keys, select "Create RAID Volume" to enter the creation screen.
The default 128KB stripe size is fine for most desktop applications. If youre running databases with small data items, you may want a smaller stripe size.
All navigation uses the cursor keys, space bar, and Enter keys. You select the drives by pressing the space bar, then moving down the list with the cursor key to the next drive.
Were using a pair of 74GB, Western Digital Raptor drives in our array. So lets size our RAID 0 volume to 70GB, which is about half the maximum.
Now lets move on to the second array.
