Maximum Disk Capacity in DS1821+

I understand the volume size limit of 108TB. However, when reading the DS1821+ user manual, it states that the maximum total disk space is 128TB. This apparent limitation is not mentioned in any of the spec sheets, etc. With the new large size size HDDs available (e.g., 24TB), I’m wondering if can exceed the 128TB limit, or if there’s some true hardware or software limitation that means the NAS cannot deal with more 128TB total capacity, even if volume size is kept to 108TB or less. Thanks for any guidance Will or others might have on this topic.

You may have multiple 108 TB volumes. There is no limit on drive size presently.
