Mirroring vs Raid
My Windows 7 is currently installed on a raid 1 array. I am considering on switching from hardware raid to windows 7's mirroring function as hardware raid tends to be problematic if the motherboard dies or is replaced. I am however curious on a number of issues.
First of all, is this a good idea at all. Will I suffer a very serious performance loss? Minor losses aren't that big of a deal but I don't want to regret this. Is windows 7 mirroring a "true" mirroring?
Are both disks bootable? Consider the main disk dying. In RAID 1 I can simply boot without doing anything (aside from pulling out the dead drive). If my main drive dies will the mirror be bootable?
How good is it in terms of avoiding data corruption or loss?
Does windows 7 mirroring provide a performance gain (during read)? It could be twice as fast as there are two disks to read from...
I am planning on making this switch without reinstalling windows. I basically plan on pulling one of the raid disks off the array, format it. Boot from the other disk in raid... Use windows 7 mirroring to make a carbon copy. Remove the remaining disk in raid. Boot from the mirror. And finally use windows mirroring function on the original raid'ed drive.
