Reliability RAID 1 vs RAID 10

For the same storage capacity, given that a RAID 10 consists of two RAID 1 arrays, is RAID 10 at least twice as likely to fail?

However, as the four drives in the RAID 10 will be half the capacity of the two drives in the RAID 1, will this also half the chance of a drive failure during rebuild? If so, there is comparable risk of failure between RAID 10 and RAID 1.

However, a RAID 10 will produce more heat and vibration than RAID 1 and draw more power. This will increase the failure rate of RAID 10.
