I'm looking at configuring two external Western Digital Thunderbolt Duo drive enclosures using Disk Utility's software RAID setup tool. Each enclosure houses two 2TB drives. I'm looking to get the performance of RAID 0 striping with the redundancy of RAID 1 mirroring. What I'm not sure of, and I hope someone can shed some light on, is how to combine the RAID sets to achieve my desired goal. As I see it, there are two possible ways to go about this.
The first would be to configure the master RAID set as mirrored, with the individual thunderbolt enclosures configured as striped sets. Example:
The second approach would be to configure the master RAID set as striped, with the individual thunderbolt enclosures configured as mirrored set. Example:
Can anyone tell me which is the better way to go about this? Are there advantages/disadvantages to either approach? Thanks for any insight you might have!
