HPT370 RAID : Can I stripe 2 drives and mirror 2 drives

[ProRider]

Anyone know if I can configure the HPT370 controller so that two physical drives are striped and, separately, two physical drives are mirrored?

In other words, I want a RAID 0 stripe array on two physical drives where high performance is important but redudancy is not AND I want a RAID 1 mirror array on two other physical drives where data redundancy backup is more important than performance.

Raid 0+1 is what you want, and that is supported.

1. Delete all previous setups
2. Boot you machine and enter RAID setup utility.
3. Setup one RAID 0 preferably drives 1 and 3
4. Setup another RAID 0 drives 2 and 4
5. Create RAID 0+1; there should be only two drives to pick from.
6. Exit and run FDISK
7. After FDISK; run FORMAT
8. 8K Clusters ---> Maximum partition of 16 GB
16K Clusters --> Maximum partition of 32 GB
32K Clusters --> Maximum partition of 64 GB
9. To achieve the correct FORMAT; for example if your drive whether or not its partitioned. During format utility if your C Drive is less than 16 gigabytes, type in at A:/FORMAT C: /Z:16

Thanks guys - just to be clear:

A. I want to use two drives in a RAID 0 stripe array for performance without redundancy. This is for digital video editing. Fo this array, I would use two 60GB Maxtor DiamondMax Plus 7200 RPM drives. I thought these would be set as Master and Slave on the IDE3 channel.

B. Separately from the above, I want to mirror two other drives where redundacy and safety of data is more important than performance. For this array I would use two Western Digital 27 MB 7200 RPM drives. I thought these would be set as Master and Slave on the IDE4 channel.

There is no relationship or interaction between A and B, apart from their being on the one HPT370 controller.

Is the HPT370 controller capable of separately managing a RAID 0 stripe array (example A) and a RAID 1 mirror array (example B)?

Thanks.

Reading the documentation, I'd have to say, "yes". You'll probably have to put each raid on it's own channel, (ie - raid0 on ide3, raid1 on ide4).

actually you can do it however you want...you just have to set up the raid array by picking which ones you want...doesnt matter what ide channel you have them on or if they are master/slave or what...

Mine is set up like this:
IDE3=IBM 30 Gig (Master) and Maxtor 20 gig (slave)
IDE4=IBM 30 Gig (Master) and Maxtor 20 gig (slave)
the two IBM's are raid0 and the maxtors are mirrored...

Works great!

Thanks - this is great info.

Final question: someone mentioned documentation. I only have what came in my ABIT KT7A-RAID mobo manual. Are there any more docs for the HPT370? If so, would love copies / links.
