Running without parity in your RAID setup for a couple of months can be a viable option depending on your specific needs and considerations. However, it's important to understand the implications and risks involved before making a decision. Without parity, you will not have the ability to recover data in case of a drive failure during that period. If one of the 4TB drives fails, you could potentially lose the data stored on it. This means that if you don't have a backup of your data elsewhere, there is a higher risk of permanent data loss.
