RAID with 2x 500GB + 1x 1TB?

Hello everyone,

 

I am getting two WD Re drives with 500GB capacity soon and I currently have a 1TB Seagate Desktop HDD in my PC.

 

So my question is:

 

Is it possible to put the both 500gb in RAID 0 and mirror the array to the 1TB HDD (RAID 1 theoretically)

I am planning on using my "onboard" RAID controller on my ASUS X99-Pro.

 

Thanks!

Please quote me in any answers to my posts, so that I can read them easily and don´t forget about them. Thanks!

With 2 different raid  controllers I think it is theoretically possible?  But with the same raid controller I don't think it's possible 

 

edit:  scratch that, the raid zero would not show up on the second one to begin with I don't think,  they all have to be on the same controller...  So no it wouldn't work I'm pretty sure

Hi :)

 

My two cents on this: If you manage to use two different controllers for this you might get it to work. If you configure the two drives in RAID0 as a hardware RAID so the OS sees them as one volume and then configure a software RAID between the array and the other drive it may work, it depends on the controllers. 

 

Though probably possible, I wouldn't recommended as it would be quite unstable and risky for the data. I would rather do a continuous backup between the array and the single drive for the data that you consider valuable. :) But have in mind that having your data on two separate drive in the same system shouldn't really be considered a backup as it doesn't provide safety against power failure, physical damage of the case and other similar things. Also, a standalone RAID array should never be considered a backup in any case.

I will try the solution with a hardware+software RAID, thanks for the tipp!

 

And I don´t want to create the  RAID to protect the data from things that you listed, I want to do it because I get the drives used and I don´t know how stable/unstable they are. My important data is stored on my server anyway. It is more to test things out and stuff :D

 

Anyway, thank you for your tipp!

If it's for testing purposes and you have everything backed up safely elsewhere then by all means do it and post back with the results if it works. Again, as long as Disk Management sees the RAID0 as a single volume and allows Mirrored arrays, you may be able to pull this off. :) Post back when you are done testing!

I will!

 

I get the drives on the 2nd of may in the evening, so I will try it on the third and post my results.

In this case, waiting for the result. :)

 

Just a tip, before configuring the drives in a RAID array I would perform an extended test on each of them with WD Data Lifeguard Diagnostic just to make sure they are not defective nor damaged during transportation.

I do this all the time with Linux md RAID.  Two older Seagate drives (500gb and 320gb) RAID-1'ed to a Hitachi 2TB drive. 

 

I created 2 RAID-1's, but I could have RAID-0'ed the two Seagates, and then mirrored the RAID-0 to the Hitachi 2Tb with RAID-1.

 

A lot depends on the flexibility of the RAID solution you're using.
