Samsung 860 EVO 250GB M.2 SATA SSD: MJX controller, 64-layer V-NAND, up to 550MB/s read & 520MB/s write with 512MB LPDDR4 cache. High-efficiency cable-free storage for compact systems.
Product Details
Overview
The Samsung V-NAND SSD 860 EVO M.2 250GB delivers uncompromising solid-state reliability engineered into a space-saving M.2 2280 form factor. Utilizing Samsung's advanced 64-layer 3D V-NAND technology paired with the refined Samsung MJX controller, this drive brings top-tier SATA performance without the clutter of traditional 2.5-inch drive bays and SATA data/power cabling. Designed for seamless system integration, it optimizes thermal dissipation and power efficiency directly from the motherboard slot.
Architecture & Performance
Built on the saturated SATA III 6Gb/s interface, the 860 EVO operates at the absolute ceiling of the bus standard. Driven by the Samsung MJX controller and backed by 512MB of dedicated low-power LPDDR4 DRAM, the drive executes multi-threaded host communications effortlessly. Samsung's Intelligent TurboWrite technology utilizes an elastic SLC buffer to accelerate workloads, pushing sequential read speeds up to 550 MB/s and sequential write speeds up to 520 MB/s. For everyday responsiveness and multi-tasking under OS environments, it achieves random 4K read and write speeds of up to 97,000 IOPS and 88,000 IOPS respectively.
