Hi Neto,
RAID 0 to store production data should never be used. Never a good idea, in my opinion.
Simple reason is that when you lose one disk, you lose everything.
If your goal is to bench the disk, go for single disk.
If you want to be closer to a production setup, go for RAID 10, or pick a RAID setup close to what your needs and
capabilitiesare (more reads? more writes? SSD? HDD? cache? ...? )
If you only have 2 disks, your obliged (redundant) choice is RAID 1.
