Hi, I have a 2012 Mac Pro tower (with 4 drive bays), running MacOSX 10.9.4 (the latest version of Mavericks).
Can I use Apple's Disk Utility to create a RAID10 disk array? That is, could I put 4 equal-sized hard drives in the Mac Pro tower and then use Disk Utility to create a RAID10 setup, which is a stripe of mirrors? If this is possible, should it be nearly as good as a commercial software RAID solution, as long as I am happy with RAID10 and do not care about RAID5 or RAID6? I know that Disk Utility does RAID0 and RAID1, but I do not know whether it can be used to combine those software RAIDs. For example, suppose my 4 hard drives are named Disk1, Disk2, Disk3, and Disk4. I was wondering if I could use Disk Utility to combine Disk1 and Disk2 (via RAID1) into Mirror1, and likewise combine Disk3 and Disk4 (via RAID1) into Mirror2, and then combine Mirror1 and Mirror2 (via RAID0) into StripedDisk. In particular, if all disks are 3 TB, then I was hoping to end up with a 6-TB RAID10 disk array, which would be a stripe of two 3-TB mirrors. If this is possible, would you trust it? I figure all disks must be the same size, but do they have to be identical? In my case, they would all be Seagates and all have the same nominal sizes and speeds, but the exact models (and therefore exact sizes to the byte) might differ. Thanks in advance for any help you can provide.
