Is this possible and if so how?

post #1 of 6
Thread Starter 
Hi all,

So I realized I am terrible at backing things up and never keep any of my data. I'm doing a new build soon and I have a proposed idea in my head and want to see if it would work.

I want to have 2 SSDs in RAID-0 with Win7 installed and other critical apps.

Also, I want to have 2 1TB Caviar Blacks in RAID-1 for Data and such. These drives will have their own Program Files and (x86) folders for games and other apps.

Now, lets say the SSDs are 80GB each for an 160GB array. Can I create a 165GBish partition on the RAID-1 array and use that to backup the two SSDs? The important thing here is that, if the RIAD-0 array fails, I want the RAID-1 array to boot and be functional from the partition.

Possible? Better option?

If I remember correctly, its called RAID Nesting, and its RAID 1-0 I believe, or otherwise known as RAID 10. for the setup you want.

Its probably in your Hardware RAID manager listed as Raid 10. Just check it out in the setup.

If you put the SSD's in a RAID array with regular hard drives, it will bottleneck the speed of the SSD's rendering them completely useless.

Exactly. That is why I don't want a nested array. I'm talking about two separate RAID arrays, or for that matter just ignore the RAID-1 and pretend it was 1 drive.

I'm sorry. I'm not sure I understand what you're trying to do. You want a RAID array of SSD's to be backed up by a RAID array of HDD's? Maybe I'm missing something...

For simplicity sake, lets say no RAID is involved at all. I have a small SSD and a big HDD. I want to make a partition on the HDD about the same size as the SSD, and backup everything to it from the SSD (not necessarily mirror it, maybe once a week backup), including the operating system. If the SSD were to fail, I want the system to still boot from the single HDD. Example:

SSD contains Win7 and programs.
HDD contains programs and data.
SSD is backed up onto partition on the HDD that is roughly the same size.
SSD fails.
Computer boots from HDD partition and all data is safe.
