| Best rig (GAMING — whole PC) | 10,171 | 13,170 |
| Sequential read | 4,473 MB/s | 1,698 MB/s |
| 4K IOPS | 22,565 | 8,961 |
| 4K latency, median (lower is better) | 41 µs | 116 µs |
| Type | NVMe SSD | NVMe SSD |
| Size | 1 TB | 2 TB |
What the numbers mean
The headline score is the part's best measured run, and the measurements under it come from that same run. It shows what the part has been proven to do — not what an average rig gets out of it. The drive score is the system drive's measured performance in the rigs it sat in — sequential read and 4K IOPS, unbuffered. PCIe generation, fill level and driver affect it. GAMING is the whole rig's score. We show both and never mix them.
All numbers come from our benchmark suite, the same test on every PC, written in Rust with no middleware. The methodology is open at https://whatfps.com/metodik
