Samsung SSD PM871b (OEM equivalent of 850 EVO) 512GB 94% HealthCheck out my other drives available on !
The Samsung PM871b is the OEM equivalent of the retail Samsung 850 EVO.

• Hardware Profile: Under the hood, it features the same 64-layer 3D TLC V-NAND and an optimized variation of the MGX controller found in late-revision 850 EVOs and early 860 EVOs.
• Performance Profile: It shares the same performance characteristics as the 850 EVO, including relying on a pseudo-SLC TurboWrite cache to achieve its maximum SATA speeds before dropping down on sustained writes.

The primary differences are that the PM871b uses business-oriented OEM firmware managed by computer manufacturers (like Dell, HP, or Lenovo) andlacks support from the retail Samsung Magician software.The Samsung PM871b is an OEM (Original Equipment Manufacturer) solid-state drive released around 2017 and designed primarily for business laptops, prebuilt desktops, and embedded systems.Key Specifications
