Our take on the Samsung 9100 Pro 4TB PCIe 5.0x4 M.2 2280 Internal SSD
The Samsung 9100 Pro is a 4TB NVMe SSD on the PCIe 5.0 x4 interface in the M.2 2280 form factor. It is Samsung's flagship consumer drive, built for sequential reads in the 14,000 MB/s class and writes around 13,000 MB/s, roughly double the PCIe 4.0 drives it replaces. The 4TB model carries a large dynamic cache and high endurance, so it suits large game libraries, video editing and workstation use. Against PCIe 4.0 rivals it is faster but runs warmer and needs a heatsink or good motherboard cooling; against other PCIe 5.0 drives it is among the most consistent, though it is not the cheapest per terabyte.
- Sequential reads around 14,000 MB/s, among the fastest consumer SSDs
- 4TB capacity in a single M.2 slot
- High endurance rating for heavy writes
- Samsung's Magician software and long warranty
- Consistent performance with a large dynamic cache

What reviewers say
Reviewers rate the 9100 Pro as one of the fastest consumer SSDs available, with near-top sequential and random speeds. Owners praise the capacity and reliability but note heat and the need for a heatsink.
- SpeedPraisedReviewers measure sequential reads near the top of the PCIe 5.0 class.
- HeatCriticisedOwners report the drive runs hot and needs a heatsink under long writes.
- CapacityPraisedThe 4TB model lets users keep games and footage on a single drive.
Questions and answers
- Is the Samsung 9100 Pro worth it over a PCIe 4.0 SSD?
- Only if your motherboard has a PCIe 5.0 M.2 slot and you move large files or play big games. On a PCIe 4.0 slot it runs at PCIe 4.0 speeds, so the gain is small.
- Does it need a heatsink?
- Under sustained writes it gets hot, so a heatsink is recommended. Many PCIe 5.0 motherboards include one; the PS5 needs a heatsink that fits its bay.
- Is it compatible with a PS5?
- Yes, it is an M.2 2280 NVMe drive, and the PS5 accepts that form factor. A low-profile heatsink is required to fit the console's expansion bay.
- How does it compare with the 990 Pro?
- The 9100 Pro is the newer PCIe 5.0 drive and is roughly twice as fast in sequential transfers. The 990 Pro is PCIe 4.0 and runs cooler and cheaper.
- What is the endurance rating of the 4TB model?
- Samsung rates the 4TB drive for about 4,800 TBW, which is high for consumer use. It also carries a five-year limited warranty.
- What comes in the box?
- The drive itself and documentation. A heatsink and mounting screw are not always included, so check your motherboard's M.2 hardware.
