8TB is the maximum the PS5 supports on current firmware and holds about 106 big games at an average of 75GB each. The field is small because few Gen4 M.2 drives reach this size with a low-profile heatsink, and the price per terabyte is usually higher than 2TB or 4TB. It is for owners who never want to think about storage again.

Who an 8TB PS5 SSD suits
8TB is a niche, maximalist choice. It makes sense only if you keep an enormous library permanently installed and value never deleting over cost per terabyte.
Few drives qualify. Reaching 8TB in the M.2 2280 form factor with a heatsink under 11.25 mm narrows the field, so expect a small selection and premium pricing.
Is 8TB worth it?
Choose 8TB if
- You want every game you own installed at once.
- You never want to manage storage again.
- The convenience premium does not bother you.
Consider 4TB instead if
- You want far better price per terabyte.
- A 50-plus game capacity is already plenty.
- You want a wider choice of drives.
