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.
