Mac Pro :: Using Multi Leo/Vista Boot RAID0 Arrays From SSDs

As we discussed in other threads it could be particularly advantageous to use SSD RAID0 arrays for dual or even multiple booting. With a decent amount of striped SSDs the idea is to run all your operating systems and applications with high speed. At least that is the theory. To test the idea I have decided to use two Maxtor 160 GB HDD in a very basic dual RAID0 array configuration for booting OS X and Vista-64 in AHCI mode.

Here we go:

First thing I learned is that you have to partition the HDDs prior to building your array.

Second thing I learned is that you have to keep it all in HFS+ to make it work.

So now I have used disk utility to create two equal size partitions in HFS+ with GPT on both HDDs.

Next I fused the two lower partions together for a first RAID0 array named 2R-Leo. Format is still set to HFS+ and RAID0 mode is selected.

Then I fused the two upper partitions together for a second RAID0 array named 2R-Vista. Here format is also set to HFS+ and RAID0 mode is selected.

With that done I exited the disk utility to get a fresh start on it. I then entered disk utility again.
