Benchmark Results (GPD WIN 5 — PCIe 4x1 bottleneck)
- CrystalDiskMark: 1785 MB/s read, 1744 MB/s write
- AS SSD: Read 1470, Write 1632, Overall 3855
- ATTO: From 44/41 MB/s (512 B) to 1.66/1.63 GB/s (64 MB files)
Note: GPD WIN 5 uses PCIe 4x1 (max ~2000 MB/s). Full PCIe 4x2 would achieve 3700+ MB/s.
Device Compatibility
Currently confirmed: gpd-win-5, ONEXPLAYER Super X (announced).
Verdict
Revolutionary compact storage. Massive leap over MicroSD (~100 MB/s). Bottlenecked by WIN 5’s 4x1 interface — full potential awaits PCIe 4x2 devices.
