Samsung PM9C1b MZVL8512HFLU-00BLL vs Samsung PM9C1b MZVL81T0HFLB-00BH1 vs SK Hynix PVC10 HFS001TEM4X169N

Samsung PM9C1b MZVL8512HFLU-00BLL

► remove from comparison PM9C1b MZVL8512HFLU-00BLL

The Samsung PM9C1b MZVL8512HFLU-00BLL (MZ-VL8512T0D) is a 512-GB NVMe PCIe 4 x4 SSD that never received an official launch. Supposedly, PM9C1b drives are based on the same hardware as 990 Evo Plus models but are meant for OEMs rather than general consumers.

The 22 by 80 format drive first became available in 2024, with Notebookcheck editors only getting their hands on one in March 2026.

Performance

AS SSD reports a sequential read rate of 5.18 GB/s, with writes a little slower at 4.6 GB/s. These are decent figures for a mid-range drive in early 2026. Its performance sustainability seems reasonably good, too.

Samsung PM9C1b MZVL81T0HFLB-00BH1

► remove from comparison PM9C1b MZVL81T0HFLB-00BH1

The Samsung PM9C1b MZVL81T0HFLB-00BH1 is a 1-TB NVMe PCIe 4 x4 SSD that never received an official launch; supposedly, PM9C1b drives are based on the same hardware as 990 Evo Plus models but are meant for OEMs rather than general consumers.

The 22 by 80 format drive first became available in 2024, with Notebookcheck editors only getting their hands on one in September 2025.

Performance

AS SSD reports a sequential read rate of 4.6 GB/s, with writes a quarter slower at 3.25 GB/s. These are decent figures for a lower mid-range drive in late 2025. Its performance sustainability proved reasonably good, as long as one ignores a curious dip at the very beginning.

SK Hynix PVC10 HFS001TEM4X169N

► remove from comparison HFS001TEM4X169N

A 1024 GB PVC10 series PCIe 4 x4 NVMe SSD that appears to have been quietly launched some time in H1 2024. The HFS001TEM4X169N is the M.2 2242 Gen 4x4 variant and delivers decent sequential read rates (AS SSD: 5.1 GB/s). Its sequential write rates are significantly lower with around 2.3 GB/s, though.
