onboard Raid0+1

[tale]

Hi,

If you have used onboard RAID with Abit or Asus mobos before, how does RAID0+1 works? The manual stated 4 harddrive devices are required.

Does the RAID0+1 use all 4 IDE slots, 1 device per slot or 2 IDE slots with Primary Master, Primary Slave, Secondary Master, and Secondary Slave?

Thanks.

0+1 is just the merger of RAID 0 and 1.
like two parallel RAID 0 arrays, one array for data, one for backup.

but no. most onboard raid systems only have 2 channels, meaning that all 4 drives must be on the two cables, master and slave.

the exception is the onboard raid for the abit kt33 motherboard. it has 4 RAID channels, so you can spread the 4 drives out, one per channel.

read the HDD FAQ for some good links.

Yeah, strictly speaking, Raid0 doesn't exist. There's nothing redundant about it; one drive goez out, you are completely screwed.

0+1 (called 10 sometimes) is another non-existant term, but who really carez. You have a raid0 config across two drives, then the exact same raid0 config again.

Which gives you some backup. If one drive failz, that raid0 config is toast. But you have another raid0 config which is identical (mirrored).

Spanning, Striping, Mirroring. Span and stripe are not raid. Mirroring is, and it's raid1. Striping is what is called raid0.
