I have now installed a RocketRaid 2680 controller and set up a RAID5 for all my data to be stored on.
Unfortunately I now cannot boot from the RAID1 anymore, the PC is trying…

My motherboard, an Asus M4a79t Deluxe, advertises RAID 0/1/5 capabilities. My limited understanding is that onboard RAID is better than software RAID. Is this necessarily true? Is an onboard RAID controller closer in performance to a software controller or a dedicated hardware controller?

When using the SQLIO benchmark tool on a 4-core Dell server with 6 15k 450GB (fast) drives, RAID 0, we found the max throughput was 2MB per second. But when configured as RAID 5, we get 30 MB per second.

Is it recommended to use software RAID-1 in a production environment? Due to budget constraints, I cannot get a hardware RAID controller for a new server.

I recently got a new laptop (Asus G73JH-A2) which has two identical hard drives in it. Unfortunately the motherboard does not have a RAID controller. What I would like to do is run the drives in a RAID-0 configuration to improve performance (plus get the extra capacity on one partition). I would…

Only thing is, I cannot get the RAID array rebuilt (not even sure it needs rebuilding, might just need the /dev/md0 mapping created... but I don't even know how to determine…

I created a mirrored RAID set using Disk Utility with those two drives, all went fine.
I was then asking myself if this is really a good idea. I know that an hardware RAID system would…
