SAMSUNG MZ-VLB2560 PM981 SERIES 256GB NVME SOLID STATE DRIVE
The Samsung MZ-VLB2560 PM981 Series 256GB NVMe M.2 2280 internal hard drive includes 64-layer 3D TLC, but the drive's small capacity and SATA interface were limiting how well we could measure the performance improvements that the new NAND enabled. The SSD also delivers a healthy performance improvement for generations due to the combination of a new controller and Samsung's new 64-layer 3D TLC NAND 3D.
Samsung PM981 offers more high performance than almost any other TLC-based SSD drive. The fastest 256GB capacity is almost completely immune from the usual risks of using TLC NAND; It's almost impossible for a real world workload to cause some kind of bad slowdown which usually indicates a full SLC write cache or something else causing a lot of background work for an SSD controller.
