Who a 1TB PS5 upgrade suits
1TB is the budget entry point. It roughly doubles your usable space for the lowest upfront cost, which is ideal if you keep a small rotation of active games and are happy to reinstall the occasional title from your library. For a casual player with three or four current games, 1TB removes the constant storage juggling without overspending.
If you install many large games, play a lot of multiplayer titles that balloon over time, or want headroom for 200GB releases like GTA 6, step up to 2TB. The price per terabyte is usually better at 2TB and the extra room pays off quickly.
Spec and heatsink requirements
A PS5 1TB drive must be M.2 NVMe Gen4 or Gen5, read 5,500 MB/s or faster, and use a heatsink that keeps the total stack under 11.25mm. Single-sided 1TB drives run cool and almost always fit a low-profile heatsink, so 1TB is the easiest capacity to get right.
The table above ranks in-stock 1TB drives by price per terabyte. A bare drive plus a cheap thin heatsink is often the lowest cost, but a model sold with a heatsink removes any doubt about fit.
