Hello,

1. Am I able to change drives in my My Passport Pro Portable RAID Storage 4TB? I would like to increase the capacity to 6-8TB. Is it possible? If yes, where can I find disk compatibility list?

2. Is it possible to encrypt this storage in stripe raid configuration on macOS? I tried to encrypt it unsuccessfully.

Thank you  
Radek
