Stripe size is pretty irrelevant on RAID 1 since all requests will be met by a single drive. If you were using RAID 5 or RAID 10 then you should set the stripe element size to the database block size, for example with MS SQL you would use 64K stripe size, then so long as the partition is aligned properly each I/O is met by a request to a single disk.
