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.

Dell XPS 14 2026 review: Fully reborn with Intel Panther Lake X7

The XPS series has gone through some bumps on the road, but the latest Panther Lake XPS 14 puts the family back on track to be a much easier recommendation than any recent predecessor.

Lenovo ThinkPad E14 Gen 7 review - Lunar Lake delivers longer battery life but brings trade-offs

We tested the ThinkPad E14 Gen 7 equipped with Intel’s Lunar Lake chip, which improves battery life but lags behind in CPU performance and limits maintenance options. This raises the question: is the Arrow Lake variant the better overall choice?

The best budget gamer? HP Omen 16 laptop review

With the introduction of the Omen Max in early 2025, HP has split its gaming lineup: the Max models are thicker but faster, while the regular Omen series now targets the budget segment. As a result, HP made several adjustments to the new Omen 16. But does this “budgetification” come with any real advantages? Let’s find out.
