Hi, I just bought a new Mac Pro and a 4-bay thunderbolt hard drive enclosure.
I used four 3-TB drives and Apple's Disk Utility to create a 6-TB array, which I believe is the equivalent of a RAID10 set. First I created 2 mirrors (3-TB each), and then I striped those to obtain a 6-TB array. I think that a stripe of mirrors is supposed to be a RAID10 set. I have 2 questions: 1. When creating the RAID sets, there was an option to choose the block size. The choices were 16K, 32K, 64K, 128K, or 256K. When the panel came up, it was set to 32K, which I assume is the default. I left it at 32K, but I was just wondering what value others might recommend. I know it depends on what I do with my Mac Pro, but I just wanted to make sure that 32K was a reasonable choice. I work with large videos once in a while, but rarely. Usually I just work with small files. Is 32K a good choice? 2. I was thinking that I would create this RAID10 "disk" and then partition it, but there is no partition tab in Disk Utility for the RAID set. Is there a way to partition the 6-TB array, or do I have to start over and partition all 4 individual drives and then combine the various pieces into separate RAID sets? That sounds painful.
