SAMSUNG RM0C0_UA 512GB M.2 2280 Nvme internal SSD

512 GB NVMe drive for system builders

This 512 GB internal SSD uses the M.2 2280 form factor and a PCI Express 3.0 x4 interface. It belongs to the Samsung PM9A1 series and carries the model number RM0C0_UA. The drive is intended for notebook or desktop upgrades that require NVMe protocol support.

Sustained write behaviour with TLC flash

The drive employs TLC NAND memory managed by firmware version 36304029. Under continuous write workloads the controller maintains steady throughput after any initial cache region is filled. Performance scales with the PCIe 3.0 x4 link width rather than bursting to a higher peak.

Thermals noise and power in typical use

With no moving parts the SSD produces zero audible noise during operation. Power draw stays within the limits of the M.2 slot specification for PCIe 3.0 x4 devices. Heat output is modest enough for standard motherboard or laptop thermal pads without extra cooling.
