Migrate raid5 array from Intel to nvidia chipset?

[yegor]

My Maximus Formula seemed to have failed. Press the power button, it runs for 2 seconds and shuts off.

I have a 4 drive RAID5 array, thats about 1TB.

I have a nvidia 680i handy, so I can put all my stuff on it. How would I migrate the array to a new chipset?

AFAIK you can't

Two different raid chipsets means you'd have to rebuilt the array from scratch.

and lose critical data in the process.

So does this mean I need to have an identical working mobo, or just one with an Intel chipset?

You need to have one of a similar or compatible raid chipset. Even then there is no 100% guarantee that its going to work.

RAID increases complexity which actually decreases reliability.. However (other than R0) it allows for continued uptime in the event of a drive failure (the only thing it helps).. RAID 0 increases performance again at decreased reliability.

I see all these people using RAID and thinking they are improving the security of their data, when in fact they are decreasing it, especially if they don't have a good backup plan. (RAID increases the need for backups, not decreases) One could argue that RAID 1 doesn't have the added complexity issue, but it still doesn't replace backup.

As for your problem, your best bet is the most similar MB you can find. It must at least be compatible (so be sure it is at least a RAID capable chipset, not all Intels are, and the same or newer is more likely than an older generation)

this is why you should not use software onboard raid. Software raid is ok if its software which will run on any hardware (linux mdmraid) but if you ever plan to replace a motherboard and keep your data you should have bought a hardware raid controller.
