SSD Controller
Samsung Polaris
Samsung PCIe 3.0 x4, NVMe 1.2 28nm (Samsung) 2 drives in database
Polaris was Samsung's in-house NVMe controller used in the 960 EVO and 960 Pro, released in 2016. It was Samsung's second-generation NVMe controller and the first with wide consumer availability, following the UBX used in the somewhat less ubiquitous 950 Pro and SM951.
Polaris supports PCIe 3.0 x4 and NVMe 1.2, and is paired with Samsung's own V-NAND. In the 960 Pro, it drives MLC V-NAND for maximum endurance, while the 960 EVO uses TLC with a variable SLC write cache (TurboWrite). The controller is a multi-core ARM design manufactured in Samsung's own fab.
