Which Configuration is Best
?"> Matrix RAID is available on any motherboard or system with the ICH6R I/O controller hub—its not restricted to Intel motherboards. However, well use Intels latest 925XE motherboard, the D925XECV2. We need to zero in on the RAID BIOS, which will be the same on any motherboard using ICH6R, including Taiwanese boards. Before we launch into the intricacies of the BIOS, you need to decide how you want to configure your RAID drives. Intels Matrix RAID feature lets you create two RAID volumes using one pair of drives. As-suming you want to create more than one RAID volume, here are your options:The first RAID volume created usually uses the outer tracks of the hard drive. That means if you use the RAID 1 volume as the boot drive, then the RAID 0 array be built using the slower, inner tracks. Of course, you could simply set up a small RAID 0 array to be the boot drive, and use the RAID 1 volume as your data drive. It all depends on what youre trying to accomplish. If all you want is a fast volume for Photoshop scratch files, editing DV capture files, or Windows swap files, then creating the RAID 0 array second will still net some performance gain. Now that weve visited configuration issues, lets roll up our sleeves and create a pair of arrays.
- Two drives in a RAID 0 array
- Two drives in a RAID 1 array
- One RAID 1 and one RAID 0, RAID 0 drive bootable
- One RAID 0 and one RAID 1, RAID 1 drive bootable
This is a critical point for Windows users, because Windows will only install on the first RAID volume created in the RAID BIOS. So if you want to boot from RAID 0, to benefit from faster boot and load times, then youll want to install Windows on the RAID 0 drive. If you want the bootable drive to be the safer one, then youll want RAID 1 to be the boot drive. That way, if one drive dies, youll still be able to boot into Windows. But you will lose anything on the RAID 0 volume.
