Samsung 870 Evo 250GB Internal SSD

The Samsung 870 EVO 250GB Internal SSD (model MZ-77E250BW) is a 2.5-inch SATA drive designed for users who want a reliable, high-performance storage upgrade for a desktop PC or laptop. Built on Samsung’s 6th Generation V-NAND technology and paired with the MKX controller, the 870 EVO delivers sequential read speeds of up to 560 MB/s and sequential write speeds of up to 530 MB/s — reaching the practical ceiling of the SATA interface. For everyday workloads and random access tasks, it achieves up to 98,000 IOPS on random reads and up to 88,000 IOPS on random writes (both measured at QD32, 4KB block size). Intelligent TurboWrite technology accelerates burst write performance and helps sustain throughput over time by using a variable write buffer that adapts to workload demands. Endurance and reliability are central to the 870 EVO’s design. The drive is rated to 150 TBW (terabytes written) and carries a mean time between failures (MTBF) rating of 1.5 million hours. It supports AES 256-bit hardware encryption, TCG/Opal, and IEEE 1667 (Encrypted Drive) security standards, making it suitable for users with data-protection requirements. TRIM, S.M.A.R.T., and auto garbage collection are all supported to maintain long-term drive health. Installation is straightforward for any system with a standard 2.5-inch SATA bay — compatible with a wide range of chipsets, motherboards, NAS enclosures, and video recording devices. Samsung’s free Magician software provides drive health monitoring, firmware updates, and performance benchmarking, while the included Data Migration Software simplifies transferring an existing OS or data from an older drive.
