RAID1 disk recovery, Z77X-UD4H

RAID1 disk recovery, Z77X-UD4H
« on: May 05, 2016, 12:13:51 pm »
In my current setup, I have 1x HDD Seagate 2TB (ST2000DM001).

I'm going to put some important data on it and I've been thinking of buying the second HDD (same model) for setting up RAID1. This would be for redundancy and being resistant to the loss of data.

Does someone know if, in case of HDD failure, I would be able to swap the failed HDD and add the new one in to the existing HDD, so it will create the new RAID1 from data existing on undamaged HDD? Not sure if that would be possible with Intel Z77 Express or Marvell 88SE9172?

I'm going to buy 2x SSD and create RAID1 with them too so would be really good to know.

Thanks

Greetings,
Yes, this is possible.  When one of the disk members in a RAID1 arrays fails, drops, goes offline, the array goes into a mode called "degraded".  The system, will boot, and run, but there is no additional protection or redundancy.  To resolve, you add a new disk.  The RAID set can be rebuilt easily in the RAID Configuration Utility.  This is true for either controller on this board.

Please remember, RAID is not a replacement for backing up your data on a regular basis.   ;)

Thank you for your answer.

Good to know it would work.

I haven't decided yet if I would use this method or I would buy redundant drives and use windows backup. The 3rd option is to use RAID1 in Windows. Maybe it's not as good as RAID configured in controller but it would survive motherboard issue I think, as the RAID configuration would be stored in Windows, not in controller.

Your MB has two controllers, both of which support RAID 1.  You can use either.  The process for recovery is identical. 

Important data should be backed up to two or more locations.
