Samsung MZ‑77E4T0B/AM 870 EVO 4TB SATA SSD

Overview

The Samsung 870 EVO internal solid‑state drive with part number MZ‑77E4T0B/AM is a 2.5‑inch SATA III (6 Gb/s) SSD designed for mainstream storage in desktops, workstations, notebooks, and storage systems. It targets environments where reliable, high‑capacity storage with SATA compatibility is required for large file storage, OS boot, and application responsiveness. The 4 TB capacity addresses large datasets, multimedia projects, VM images, and archival storage needs without moving parts, reducing vibration and latency compared with spinning media.

This drive achieves maximum sequential read speeds of approximately 560 MB/s and sequential write speeds of up to 530 MB/s over the SATA interface, consistent with SATA III throughput limits. It uses V‑NAND technology with an MKX controller and includes a 4 GB LPDDR4 cache to sustain performance under mixed workloads.

Engineered for broad compatibility, it functions in consumer desktops, enterprise SSD slots on supported motherboards, and expandable storage bays in network appliances and NAS devices that support SATA 6 Gb/s drives. Its performance characteristics make it suitable for general compute, media libraries, and database storage where NVMe is not supported.

Endurance is rated up to 2400 TB total bytes written (TBW) under typical workloads, backed by Samsung’s limited five‑year warranty (or until the endurance rating is reached). The drive also supports AES 256‑bit hardware encryption, TRIM, SMART, and sleep modes for power efficiency and reliability.

This SSD is not intended for high‑performance NVMe‑dependent server clusters or applications requiring PCIe bandwidth beyond SATA’s limits; it’s also not suited for operating in environments without proper SATA connectors or controllers.
