Samsung 870 Evo 1TB SSD

The Samsung 870 EVO 1TB 2.5-inch SATA SSD (model MZ-77E1T0BW) is a mainstream internal solid-state drive built around Samsung's 6th-generation V-NAND 3-bit MLC (TLC) memory and the in-house Samsung MKX controller. It targets desktop and laptop users who need a dependable SATA upgrade without sacrificing everyday performance. Using the SATA 6 Gb/s interface, the drive achieves sequential read speeds of up to 560 MB/s and sequential write speeds of up to 530 MB/s. Random performance reaches up to 98,000 IOPS on reads and up to 88,000 IOPS on writes (both measured at 4 KB blocks, QD32). A 512 MB low-power DDR4 SDRAM cache works alongside Samsung's Intelligent TurboWrite technology to sustain elevated write throughput during mixed workloads. The 2.5-inch, 7 mm (6.8 mm per Samsung spec) form factor fits standard laptop bays and desktop SATA slots, and the drive remains backward compatible with SATA 3 Gb/s and SATA 1.5 Gb/s hosts. Reliability credentials are strong for this class of drive. Samsung rates the 870 EVO 1TB for 600 TBW (terabytes written) endurance and 1.5 million hours MTBF. Hardware-level AES 256-bit encryption, TCG/Opal, and IEEE 1667 support are included, making it suitable for encrypted-drive deployments. The drive is backed by a 5-year limited warranty. Samsung Magician software is included for health monitoring, performance benchmarking, firmware updates, and secure erase. A separate Data Migration tool simplifies transferring an existing OS and files from a hard drive or older SSD.
