Got my new setup 11/11/25 and imagine my surprise that the H500 supports up to 16 TB of storage, but only has a 2.5" drive slot.

This might come as a shock, but right now the largest 2.5" drive you can get is an 8TB Samsung SSD and that's not cheap.

2.5" hard drives are inexpensive, but realistically max out at 5TB.

If the H500 allowed for standard 3.5" drives, hitting the 16TB maximum would be easy!
