The installation of an 8 TB SSD in the CSL VenomBox 8845HS is generally possible, provided that a free M.2 slot is available and the physical size of the SSD is compatible with the available space in the housing.

According to the manufacturer, the VenomBox supports two M.2 SSD slots, although the maximum capacity per SSD is not explicitly stated. It is mentioned in tests that up to two 4 TB SSDs (8 TB in total) can be installed. Whether a single 8 TB SSD works depends on the physical compatibility and BIOS support - there is no concrete information on this in the available data. For a definitive statement, I recommend contacting CSL support directly, as the in-house data does not contain any details on maximum SSD capacities.

Note: The configuration with 96 GB RAM and 4 TB SSD from your data indicates expandable hardware, but the SSD capacity limits are not documented.
