The best 1TB NVMe SSD in 2026 is no longer limited by PCIe 4.0. Gen5 drives now read at up to about 14,700MB/s at 1TB, while the best Gen4 drives still sit near 7,450MB/s and fit far more systems. This guide ranks 1TB NVMe drives on performance first, then on features like cache, efficiency and software.
If you want the lowest price instead, see our best budget 1TB SSD guide. All specs below are the maker's figures for the 1TB model, taken from Amazon listings on October 11, 2026. Scores are our editorial scores out of 10, not Amazon customer ratings.

Samsung SSD 9100 PRO 1TB, PCIe 5.0x4 M.2 2280
The fastest 1TB drive we found, with reads up to 14,700MB/s and writes up to 13,300MB/s, plus a 5nm controller and Samsung Magician.
Lexar 1TB NM1090 PRO NVMe SSD, PCIe Gen 5, M.2 2280
Gen5 speed with a DRAM cache: reads up to 14,000MB/s and writes up to 10,000MB/s at 1TB, with DirectStorage support.
Acer Predator GM9 1TB M.2 Gen5 SSD, PCIe 5.0, NVMe 2.0
One of the lowest-priced Gen5 1TB drives in our check, still rated for reads up to 14,500MB/s and writes up to 11,000MB/s.
Samsung SSD 990 PRO 1TB, PCIe 4.0 M.2 2280
The fastest Gen4 option here, with reads up to 7,450MB/s, writes up to 6,900MB/s and high random performance.
Lexar 1TB NM790 Internal NVMe SSD, PCIe Gen 4x4, M.2 2280
Near-flagship Gen4 reads up to 7,400MB/s and a single-sided design, for less than the 990 PRO in our check.
In-Depth Reviews
1. Samsung 9100 PRO 1TB: Best Overall
The Samsung 9100 PRO 1TB is the fastest 1TB NVMe drive we found, reading at up to 14,700MB/s and writing at up to 13,300MB/s, with random performance up to 1,850K / 2,600K IOPS.
Samsung says its 5nm controller improves power efficiency by up to 49% over the 990 PRO. You need a PCIe 5.0 slot to get the full speed; use your motherboard's M.2 heatsink.
2. Lexar NM1090 PRO 1TB: Best with DRAM Cache
The Lexar NM1090 PRO 1TB pairs a DRAM cache with an SLC dynamic cache and a 6nm controller. At 1TB it reads at up to 14,000MB/s and writes at up to 10,000MB/s.
Lexar lists Microsoft DirectStorage support. Its 1TB write speed is lower than the 2TB model's, which is common for Gen5 drives.
3. Acer Predator GM9 1TB: Best Gen5 Value
The Acer Predator GM9 1TB was one of the lowest-priced Gen5 1TB drives in our check. It is rated for reads up to 14,500MB/s and writes up to 11,000MB/s.
It is backward compatible with Gen4 slots, but at Gen4 speed. Its Amazon listing is light on other details.
4. Samsung 990 PRO 1TB: Best PCIe 4.0
For Gen4 systems, the Samsung 990 PRO 1TB is the fastest pick here at up to 7,450MB/s reads and 6,900MB/s writes. Samsung rates random performance up to 1,400K / 1,550K IOPS.
It cost about as much as some Gen5 drives in our check, so it makes the most sense if your PC has no Gen5 slot.
5. Lexar NM790 1TB: Best Gen4 Value
The Lexar NM790 1TB reads at up to 7,400MB/s and writes at up to 6,500MB/s with a single-sided design, for less than the 990 PRO in our check.
It uses HMB instead of onboard DRAM. A heatsink version is available for PS5.
How to Choose the Best 1TB NVMe SSD
Gen5 vs Gen4
Gen5 needs a PCIe 5.0 M.2 slot, found on recent AMD AM5 and some Intel boards. In a Gen4 slot it runs at Gen4 speed. If you have no Gen5 slot, a top Gen4 drive is the better buy.
Speeds Differ by Capacity
Makers often quote their highest figures for 2TB and larger models. Always check the 1TB numbers, as we did here.
Cache Design
DRAM drives like the NM1090 PRO hold speed better during long writes. HMB drives like the NM790 use less power.
Cooling
Gen5 drives run hot. Use the motherboard M.2 heatsink. For PS5, a heatsink is required.

Quick Setup Tips
- Find your slot generation: check the motherboard manual for Gen5 or Gen4 M.2 slots
- Use the top slot: the slot nearest the CPU is usually the fastest
- Avoid lane conflicts: some boards share lanes between M.2 slots and the graphics card
- Update firmware: use Samsung Magician or the maker's tool
- Keep free space: leave some room free for steady performance
Frequently Asked Questions
What is the best 1TB NVMe SSD?
The Samsung 9100 PRO 1TB for Gen5 systems, and the Samsung 990 PRO 1TB for Gen4 systems.
What is the fastest 1TB NVMe SSD?
In our check, the Samsung 9100 PRO 1TB, rated for reads up to 14,700MB/s.
Is a Gen5 1TB SSD worth it for gaming?
Only with a Gen5 slot. Games load only a little faster than on a top Gen4 drive.
Does a 1TB NVMe SSD need DRAM?
Not for most users. DRAM helps most in long, heavy file transfers.
Can I use these drives in a PS5?
The PS5 uses PCIe Gen4 and needs a heatsink. A Gen4 drive like the NM790 with heatsink is the better value there.
The Bottom Line
The Samsung 9100 PRO 1TB is the best 1TB NVMe SSD for Gen5 systems, with the Lexar NM1090 PRO 1TB for DRAM cache and the Acer Predator GM9 1TB for value. On Gen4, choose the Samsung 990 PRO 1TB or save with the Lexar NM790 1TB.
