So, right now I have a WD Raptor 10k that I'll be upgrading to an SSD in the near future. In the 3 other bays, I have 3x1TB WD Blacks. Now, I would prefer to set this up as a Raid 5 array (as a single disk for data) and use my ssd as a boot/app disk. Now I know that Disk Utility has a built in configuration for Raid 10, and that I would need a raid card to create a raid 5 array. Further, I have read up on MacZFS and believe I could make a single, backed up disk out of my 3 drives. I am just nervous about using this filesystem for business. The computer is used for graphic design. What would you guys recommend?
