vmware machines on separate disk vs RAID 0

[benq]

Hello,
I have 6 virtual machines and two identical harddrives.

I would like to ask you what is better for performance:
1. create RAID 0 and insert all 6 machines on it
2. put 3 machines to 1st disk and 3 machines to 2nd disk...

Thanks in advance for answer

I thing Raid 0 will be beneficial for you because if the data is scattered then it will become more difficult to retrieve the same and if it is not then you can have an easy access on the same.
