Are all MoBo RAID 1s created equal?

[stockhausen]

Most modern motherboards offer RAID 0 & 1 on the SATA ports.

What puzzles me is if you have say a Gigabyte motherboard with two 1TB SATA HDDs in a RAID 1 (mirrored) configuration and one of the HDDs fails:

• Could you connect the remaining HDD to some other motherboard (e.g. MSI or Asus) and still read it?
• Come to that, would you be able to read the data off that HDD installed as a normal SATA drive on any motherboard?
• Does the SATA RAID depend on the specific controller chip and/or configuration data stored on the disk?

Has anyone actually tried this in a real world (i.e. not theoretical) situation.

Much the same sort of question would apply to RAID 5 & RAID 10 but RAID 1 is the simplest scenario.

Not sure why you're asking about moving that drive to another machine etc. ...

Fair question; let me describe an alternative scenario . . .

If you have say a Gigabyte motherboard (e.g. a GA-P55A-UD3) with two 1TB SATA HDDs in a RAID 1 (mirrored) configuration and the motherboard fails:

• could you connect the remaining HDDs to some other motherboard (e.g. MSI or Asus) and still read it?
• come to that, would you be able to read the data off one or both of those HDDs installed on any (non Gigabyte) motherboard?
• does the SATA RAID depend on the specific controller chip and/or configuration data stored on the disk(s)?

My question relates really to the degree of dependence on a specific motherboard and chipset to allow reading from one or both mirrored disks.


I take it from the reply above that this configuration should be relatively safe since it relies on an Intel P55 Express Chipset?
