SK hynix PVC10 HFS256GEM4X182N

PVC10 HFS256GEM4X182N

The SK hynix HFS256GEM4X182N is a PVC10 series lower mid-range PCIe 4 x4 NVMe SSD that never received an official launch. We first tested the 256 GB drive in August 2025.

While this is an M.2 22 by 42 storage solution, 2230 and 2280 versions should be available, too.

Performance

The test SSD suffered from heavy throttling and its AS SSD sequential read/write rates closely resemble top PCIe 3.0 SSDs rather than midrange PCIe 4.0 SSDs at 3.68 and 1.43 GB/s, respectively. Its 512 GB brother delivers a much better performance.
