  Building RAID on Mac Pro

  Posted by Marcello Mazzilli on November 19, 2009 at 10:46 pm

  I just bought this eSata external case (https://www.transintl.com/store/category.cfm?Category=2696&RequestTimeOut=500).
  I would like to put 4x 1.5 Tb 7200 rpm SATA drives and then configure hem with disk utility in this way. 1st I create 2x 2disk Striped Sets (so I have 2 faster 4Tb drives). Then I want to configure one to be the mirror of the orther in Mirror mode to end up with 1 fast 4Tb drive in total (+ 4Tb automatic backup in case of disk fail).

  I know this is possible but I’ve never done it. Here it says how it’s done: https://www.macworld.com/article/57858/2007/05/june07geekfactor.html

  Can somebody help me fill in the gaps before I buy the drives?

  1) Would you suggest to go for 2Tb instead?
  2) Does the order I install the drives one on top the other affect the performance (ie 1,2,1M,2M) ?
  3) What speed will I be expecting? (double, almost double, 150%, just little more than single drive) ?
  4) Is it really safe? How will auto-recover work in the middle of a job?
  5) Any other thing I should know ?
