Doubt to Modify arrays and Strip Size /Full Strip Size/Sectors/Track and Size

[Laritza]

When you explained about the controller in my case this is HP H240 ar but I do not have saved information in the logical drive 4,that is to say in my second array B.If my second array is an independent and different bay for example bay 2, how can I add this array B with the first array A?? or in the moment that I delete array B,I create it again and then I choose level RAID 1 in array B,
will create the array B the same logical drives that the array A in the same moment with RAID 1?

Another doubt is:
When I define the RAID level 1 which are the recommended values to have in account with:

Strip Size /Full Strip Size/Sectors/Track and Size?, I am looking for about this because i need to expose some ideas and then test it in two servers,thanks in advance
