Our take on the Samsung 9100 PRO 4TB NVMe 2.0 M.2 2280 Internal SSD
The Samsung 9100 PRO is a PCIe 5.0 NVMe M.2 2280 internal SSD, and this 4TB model is the largest in the line. It is built for people who move huge files: game installs, video projects, large datasets and virtual machines. Its headline feature is PCIe 5.0 speed, roughly double the sequential reads of PCIe 4.0 drives like the 990 PRO, though real-world gains are smaller outside large sequential transfers. Buyers pick it for capacity and speed together; the trade-offs are heat and the need for a PCIe 5.0 slot to get the full benefit.
- PCIe 5.0 interface with very high sequential read and write speeds
- 4TB capacity in a single M.2 2280 stick, no second drive needed
- Samsung's own controller and V-NAND, with a long limited warranty
- Works in PCIe 4.0 and 3.0 slots at the lower link speed

What reviewers say
Owners and reviewers treat the 9100 PRO as one of the fastest consumer SSDs available, with strong sequential numbers and solid sustained performance. Most praise comes from gamers and creators moving large files, while complaints center on heat and on how little the PCIe 5.0 speed shows in ordinary tasks.
- SpeedPraisedReviewers measure sequential reads and writes well above PCIe 4.0 drives, with quick large-file copies.
- HeatCriticisedSustained writes push temperatures up, and owners say a heatsink or good airflow matters.
- ValueMixedSome buyers question whether the extra speed is worth it over cheaper PCIe 4.0 drives for daily use.
Questions and answers
- Do I need a PCIe 5.0 motherboard to use it?
- No. It fits any M.2 2280 slot and works at PCIe 4.0 or 3.0 speed there. You only get its full bandwidth on a PCIe 5.0 CPU and motherboard.
- Does it come with a heatsink?
- This is the bare M.2 2280 drive. Samsung sells separate heatsink versions; check the model name before buying if you want one included.
- Is it worth it over the 990 PRO?
- For large sequential transfers and future-proofing, yes. For gaming and everyday use the difference is small, and the 990 PRO is usually the better fit.
- Will it fit a PS5?
- It fits the PS5's M.2 slot, but Sony requires a heatsink, so use a heatsinked version or add a compatible one.
- What is in the box?
- The SSD itself and documentation. Mounting screws usually come with the motherboard, not the drive.
- How long is the warranty?
- Samsung backs the 9100 PRO with a five-year limited warranty.
