Raid 0 Not A Choice In Bios?

By Tyharo ·
I have an AsusG72Gx Laptop. It has two HDD ports and Is apparently said to be able to switch to Raid 0. I've updated my Bios and Chipset but either the choice is not there or I just cant find it. I currently have Windows 7 Home Premium 64-bit install and I am willing to reinstall windows to use Raid 0. When I enter my bios and go to my Sata configuration settings it only list IDE or AHCI. Am I missing a driver or does this laptop just not support Raid 0.
Note: Ive found a driver (Intel(R) ICH10R SATA AHCI Controller) for my laptop. I read through the read me and its mentions Raid quite a bit. I downloaded it but I have no Idea how to install it.

The three choices you'd get would be 'IDE', 'AHCI' or 'RAID'. You'd set up the RAID details later. Do you have the second drive installed? Perhaps it won't give you the option until then, although it should have...

Think REALLY hard about using RAID0 in a notebook, even if you keep awesome backups. REALLY hard...

The specs for that model do not mention RAID

It looks like the G73 supports raid, but not the G72

no Raid Choice

Theres no choice in the bios to choose Raid. I think my laptop may not support Raid like robo_dev said. Would there be anyway to add Raid support to my laptop? Or is that impossible since its a laptop?

Hardware RAID would could only be supported by the chipset since you can't add PCI devices to add a SATA RAID controller.

Google Windows 7 software RAID, you may have luck there, but as previously said, think VERY hard about striping disks especially in a laptop; hard drives fail much more commonly in laptops than desktops.

Without some insane soldering and PHD-level engineering skills, you cannot add RAID after the fact. It's built into the system board.

In theory, if a manufacturer made a mini-PCI RAID controller, which I have never seen, then with some soldering and sawing and drilling and hot-glue you could find a way to run the cables inside the laptop and maybe make it work.

If it makes you feel any better, my experience is that RAID mirroring can be flaky on a battery-operated device (or on a desktop device that can go to standby or hibernate).

The drives must be IDENTICAL, down to the firmware revision, and even then, weird bus timeouts cause the array to be degraded and have to rebuild itself more often than you would like. Errors like 'delayed write failures' are fairly common, and therefore you have to turn off write-caching, which hurts performance. RAID is great for servers, but can be a mixed bag for things that are not servers.
