Hot Spare with larger drive

With Synology Hybrid RAID (SHR), the hot spare disk needs to be equal or greater in size to the largest data disk in your array. This means that if your largest data disk is 8TB, the hot spare also needs to be at least 8TB or larger.

In your case, if you add a 10TB hot spare to your 3-drive SHR array, the extra 2TB on the hot spare disk will not be utilized. The hot spare will function as an 8TB drive and provide redundancy in case of a drive failure.
