| Drive score (the drive's own performance: sequential read + 4K IOPS) | 15,889 | 9,039 |
| Best rig (GAMING — whole PC) | 8,962 | 8,806 |
| Sequential read | 4,971 MB/s | 2,334 MB/s |
| 4K IOPS | 17,827 | 12,286 |
| 4K latency, median (lower is better) | 51 µs | 79 µs |
| Type | NVMe SSD | NVMe SSD |
| Size | 4 TB | 1 TB |
What the numbers mean
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
