SK hynix SC311 SATA 256GB

Measured performance for SK hynix SC311 SATA 256GB 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): 2,875 — measured in one rig so far, #120 of 128 measured system drives. Most often paired with Intel(R) Core(TM) i9-10900F CPU @ 2.80GHz.

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 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.
