GoodRAM CX400 256 GB

Measured performance for GoodRAM CX400 256 GB across 1 verified WhatFPS runs. Every number is measured in our benchmark suite — not estimated, not self-reported. Drive score (the drive's own performance: sequential read + 4K IOPS): 2,780 on average over the best run per rig, best run 2,780 — #89 of 91 measured system drives. Most often paired with Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz.

What the numbers mean

The GAMING score is a geometric mean of GPU (63 %), CPU (30 %), RAM (5 %) and drive (2 %) — a weak part cannot hide behind a strong one. The drive score is a geometric mean of sequential read (1 MB blocks) and random 4K read (IOPS), measured unbuffered on a 256 MB temp file on the system drive. Only the system drive is measured. The same model can differ between rigs: PCIe generation, fill level and driver all matter. Every run is HMAC-signed in the app and scored on the server.
