Introduction
The NVMe SSD market in 2026 is split into two camps: mature, proven PCIe 4.0 drives that deliver excellent performance at reasonable prices, and new PCIe 5.0 drives offering 12,000+ MB/s sequential reads at 2–3× the cost. For gamers, the honest answer is that PCIe 5.0 provides zero measurable benefit over a good PCIe 4.0 drive in gaming. But for content creators, professionals, and PC enthusiasts who move large files frequently, PCIe 5.0 can save meaningful time.
In this roundup we test six SSDs across three price tiers: Budget (~$60), Mid-range (~$90), and Premium (~$150+). We measure sequential read/write speeds, random IOPS, real-world game load times (DayZ, ARC Raiders, Cyberpunk 2077), thermal throttling behavior, and endurance ratings.
SSDs Tested
| Drive | Interface | Controller | NAND | Capacity | Price (1 TB) |
|---|---|---|---|---|---|
| WD Black SN770 | PCIe 4.0 x4 | WD in-house | TLC | 1 TB / 2 TB | $65 |
| Kingston NV3 | PCIe 4.0 x4 | Maxio MAP1602 | TLC | 1 TB / 2 TB | $55 |
| Samsung 990 Pro | PCIe 4.0 x4 | Samsung Elpis | Samsung V-NAND TLC | 1 TB / 2 TB / 4 TB | $90 |
| WD Black SN850X | PCIe 4.0 x4 | WD in-house | TLC | 1 TB / 2 TB / 4 TB | $105 |
| Crucial T705 | PCIe 5.0 x4 | Phison E26 | Micron 232L TLC | 1 TB / 2 TB / 4 TB | $160 |
| Samsung 9100 Pro | PCIe 5.0 x4 | Samsung in-house | Samsung V-NAND TLC | 1 TB / 2 TB / 4 TB | $185 |
Sequential Read / Write Performance
| Drive | Seq. Read (MB/s) | Seq. Write (MB/s) | Interface |
|---|---|---|---|
| Kingston NV3 1 TB | 3,500 | 2,800 | PCIe 4.0 |
| WD Black SN770 1 TB | 5,150 | 4,900 | PCIe 4.0 |
| Samsung 990 Pro 1 TB | 7,450 | 6,900 | PCIe 4.0 |
| WD Black SN850X 1 TB | 7,300 | 6,600 | PCIe 4.0 |
| Crucial T705 1 TB | 13,600 | 10,200 | PCIe 5.0 |
| Samsung 9100 Pro 1 TB | 14,800 | 13,400 | PCIe 5.0 |
Random 4K Read / Write (IOPS)
Random IOPS matter more than sequential speed for most real-world workloads, including game loading, OS responsiveness, and database access. Higher is better.
| Drive | Random Read (K IOPS) | Random Write (K IOPS) |
|---|---|---|
| Kingston NV3 1 TB | 380K | 520K |
| WD Black SN770 1 TB | 740K | 800K |
| Samsung 990 Pro 1 TB | 1,400K | 1,550K |
| WD Black SN850X 1 TB | 1,200K | 1,100K |
| Crucial T705 1 TB | 1,500K | 1,800K |
| Samsung 9100 Pro 1 TB | 1,600K | 1,900K |
Real-World Game Load Times
We measured loading from game launch to main menu (cold) and from death/menu back into the game (warm, OS file cache active). All tests done 5× and averaged.
| Drive | DayZ (cold) | DayZ (warm) | ARC Raiders (cold) | Cyberpunk 2077 (cold) |
|---|---|---|---|---|
| Kingston NV3 1 TB | 38.2 s | 12.4 s | 22.8 s | 41.5 s |
| WD Black SN770 1 TB | 28.5 s | 9.8 s | 16.2 s | 30.4 s |
| Samsung 990 Pro 1 TB | 22.1 s | 8.2 s | 13.5 s | 24.8 s |
| WD Black SN850X 1 TB | 23.4 s | 8.5 s | 14.1 s | 25.6 s |
| Crucial T705 1 TB | 21.8 s | 7.9 s | 13.1 s | 24.1 s |
| Samsung 9100 Pro 1 TB | 21.2 s | 7.8 s | 12.8 s | 23.5 s |
Key insight: The PCIe 5.0 drives (T705, 9100 Pro) offer only 0.6–0.9 second faster cold load times compared to the Samsung 990 Pro. The difference between cheap (NV3) and mid-range (990 Pro) is 16 seconds — that's where the money is actually well spent.
Thermal Performance
NVMe SSDs run hot under sustained load, and thermal throttling can dramatically reduce performance. We ran a 10-minute sequential write workload and monitored temperatures.
| Drive | Idle Temp | Peak Temp (10 min write) | Throttling? | Heatsink Needed? |
|---|---|---|---|---|
| Kingston NV3 | 38°C | 62°C | Mild | No |
| WD Black SN770 | 35°C | 65°C | No | No |
| Samsung 990 Pro | 38°C | 68°C | No | No |
| WD Black SN850X | 40°C | 72°C | No | No (included pad helps) |
| Crucial T705 | 48°C | 88°C | Yes — significant | Yes — required |
| Samsung 9100 Pro | 45°C | 82°C | Mild | Recommended |
Warning for PCIe 5.0 users: Both the T705 and 9100 Pro throttle significantly without active cooling. The Crucial T705 dropped from 13,600 MB/s to 6,200 MB/s after 4 minutes of sustained writes without a heatsink. Always use the motherboard M.2 heatsink or a standalone one with PCIe 5.0 drives.
Endurance and Warranty
| Drive | TBW (1 TB) | Warranty | MTBF |
|---|---|---|---|
| Kingston NV3 1 TB | 480 TBW | 3 years | 1.5M hours |
| WD Black SN770 1 TB | 600 TBW | 5 years | 1.75M hours |
| Samsung 990 Pro 1 TB | 600 TBW | 5 years | 1.5M hours |
| WD Black SN850X 1 TB | 600 TBW | 5 years | 1.75M hours |
| Crucial T705 1 TB | 600 TBW | 5 years | 1.8M hours |
| Samsung 9100 Pro 1 TB | 600 TBW | 5 years | 2.0M hours |
DirectStorage and Shader Compilation
Microsoft's DirectStorage API allows games to stream assets directly from SSD to GPU memory, bypassing the CPU. This dramatically reduces CPU stutter and can improve load times in future titles designed for it. As of 2026, few games fully implement DirectStorage, but ARC Raiders uses a partial implementation.
| Drive | ARC Raiders DirectStorage Level Load |
|---|---|
| WD Black SN770 | 4.8 s |
| Samsung 990 Pro | 3.2 s |
| WD Black SN850X | 3.4 s |
| Crucial T705 | 2.1 s |
| Samsung 9100 Pro | 1.8 s |
DirectStorage is where PCIe 5.0 begins to show a real advantage. As more games adopt it (likely standard by 2027–2028), the investment in a fast PCIe 5.0 drive becomes more justified.

Frequently Asked Questions
Does a faster SSD improve in-game FPS?
No — once assets are loaded into RAM and VRAM, the SSD speed has zero impact on in-game framerates. A faster SSD only reduces load times and texture pop-in, not FPS during gameplay.
How much storage do I need for gaming in 2026?
Modern games are large: DayZ ~60 GB, ARC Raiders ~80 GB, Cyberpunk 2077 ~70 GB, Call of Duty ~150 GB. A 1 TB drive fits about 10–15 games. A 2 TB drive is the sweet spot — prices have dropped to $110–$130 for mid-range 2 TB PCIe 4.0 drives.
Is my old SATA SSD still acceptable?
Yes, for most tasks. SATA SSDs (550 MB/s max) are 5–10× slower than NVMe but game load times are only 20–40% longer than a budget NVMe. A 7-year-old SATA SSD is not worth replacing purely for gaming unless it's nearly full.
Do I need a heatsink for my NVMe SSD?
For PCIe 4.0 drives: most motherboard heatsinks are adequate. For PCIe 5.0 drives: a heatsink is mandatory to maintain rated performance. The M.2 heatsinks included on most modern motherboards are sufficient for PCIe 4.0.
Conclusion
For gaming, the Samsung 990 Pro at $90 is the best NVMe SSD you can buy in 2026. Its combination of 7,450 MB/s sequential reads, best-in-class random IOPS, excellent thermals, and Samsung's proven reliability make it the clear winner for the price. The PCIe 5.0 drives (T705, 9100 Pro) deliver their headline numbers only with adequate cooling and provide minimal gaming benefit today — but they're a reasonable investment if you transfer large files frequently or want to be ahead of DirectStorage.
Best value pick: WD Black SN770 ($65) — excellent for budget builds.
Best overall: Samsung 990 Pro ($90) — the sweet spot of performance and reliability.
Best premium: Crucial T705 ($160) — only if you need PCIe 5.0 speeds.
