Should I boot from RAID 1?
Posted on 2010-01-09
I just finished building a new computer around the P5P43TD Pro mobo, with a Q9550 CPU, 4GB of very fast RAM, two WD RE3 drives, and one WD Caviar Black drive. This computer was built for audio and video editing. I was going to put the OS, apps, and backup (medium-term storage of projects) onto the RAID 1 array for safety, and use the Caviar Black drive as the working drive for current audio and video projects.
Firstly, is this a good idea? Is it a waste to use RAID 1 for the OS and apps, since I could always reload them. Also, presumably, there is some overhead to RAID 1... would my system run faster if I used the Caviar Black as the boot and app drive?
Secondly, if I really want fast transfer of date on working projects, I've read that solid state HD's are the fastest (some are, some aren't... I know). I'm afraid, however, that SS disks have a limited number of writes for each memory location... would it be a problem for something as data-intensive as audio and video editing? I don't need a huge drive, 16GB would be plenty. OCZ has a 30GB drive that does 135MB/s burst with 100MB/s sustained write and 240MB/s read! BUT, with potentially hundreds of writes across the same memory location on each project, I fear it won't hold up. What say ye?
I started questioning whether I should boot from RAID 1 when I ran into trouble loading the OS.
While going through POST the first time, I hit <DEL>, then <F8>, then <Ctrl-I> to get into the RAID setup and created a RAID 1 array from the two RE3 drives. I then inserted my Win7 64-bit OS disk and rebooted.
When the installation disk asked where I wanted to load the OS, it showed me Disk 0 and Disk 1, both with 465GB of unallocated space. There was a box at the bottom when Disk 0 was selected (blue highlight), which said that this drive was not acceptable for booting... that either the motherboard didn't allow it or I didn't have the right driver. When I selected Disk 1 (blue highlight), that warning message was not displayed.
So, I put the ASUS P5P43TD Pro CD into the second optical drive and clicked the <Load Driver> button on the screen. I navigated over to the CD and down to the Win7 64-bit RAID driver and selected it. The system seemed to load the driver.
When the system put me back on the page where I could select onto which disk to load the OS, Disk 0 (presumably the RAID 1 array), was still not acceptable for booting.
Am I not able to boot from RAID?
Finally, should I load all my drivers on that same screen (chipset, video, audio, ethernet, etc.) or should I wait until the OS is installed and then load the drivers?
