HP Array yes but you need to use software RAID. In other words connect the second SSD to the machine (do not involve it into any RAID).
Then go to Windows Disk Management and convert both SSDs into Dynamic Drives.
After that click on volumes of your system SSD drive and select Create Mirror.

Why software RAID? In this case the TRIM feature of the SSD drive works which is not the case when you use hardware RAID for SSD drives. That's why it is recommended to use RAID software mirror via Windows features.

Nope. It can ask to restart the system to convert the drive but usually it takes place in Windows.
