Samsung 9100 PRO 1TB PCIe 5.0 x4 NVMe M.2 2280
72 out of 100 medium confidence 11 reviews
The Samsung 9100 Pro is generally praised for its blazing-fast Gen5 speeds, with several users noting a noticeable improvement over Gen4 drives like the 990 Pro. However, one verified buyer reported a complete failure after less than two weeks, which is a significant concern. Most reviewers recommend it for high-end builds, especially with a heatsink, but caution that the speed boost may not be worth it for everyone.
Pros
- Blazing fast Gen5 speeds
- Noticeable improvement over Gen4
- Works with PCIe 4.0 boards
- Compatible with PS5 (with heatsink)
- High-quality build
Cons
- Reported failure within 2 weeks
- Requires heatsink for best performance
- Speed difference not noticeable for everyday tasks
- Not worth upgrading from Gen4 for some
