  Hi pnksys，

  Thanks for your post.

  Maybe you could refer to the document about storage space in server 2012, besides offering resiliency to drive failures, Storage Spaces also offers increased performance by striping data across multiple disks. You could refer to the articles below.

  Thank your reply Mary Dong,

  But i was read this link before post that question. Have a point confuse

  "Mirror spaces add a layer of data copies below the stripe, which means that a two-way mirror space duplicates each individual column's data onto two disks."

  If i understand right above, the architecture will like option 1 on my question: imgur.com/kvMOL3r

  but i think Windows Server must consume more performance for mirror all chunk columns.

  How do you think about that Mary Dong ?

  Hi pnksys,

  Based on my understanding, should be first columns then the raid.

  You could also check the performance for the raid in the storage space.

  Hi,

  Thanks for your feedback.

  >Could you help me about the second problem ?

  I could only say based on my knowledge, could be first the columns then the raid. As you said in first question. The column controls, for each stripe of data written, how many physical disks it writes to. From my personal view, so that column. could be first.

  You may also check the article below.
