Samsung SSD PM9A1 M.2 NVMe 512GB Review

Priced at $146.00, the Samsung SSD PM9A1 M.2 NVMe 512GB is Samsung's entry in the internal ssds category. With 15 buyers rating it at 4.0 stars, it currently sits at #45 of 45 in our rankings. It won't beat the top picks on raw rating, but at 38% below the category average price, it has a different value proposition.

For internal ssds, what you can't see matters more than what you can - the controller, NAND type, and DRAM cache determine real-world speed. The enclosure is just the wrapper. Performance ratings are mostly positive with occasional reports of throttling on long file transfers.
