Description
Overview
The Samsung 870 EVO 1TB is a 2.5‑inch SATA III internal SSD (model MZ‑77E1T0B/EU, EAN 8806090545917) designed as an upgrade for laptops and desktop PCs that use a 2.5‑inch drive bay. It uses Samsung V‑NAND (3‑bit MLC/TLC) and Samsung’s MKX controller with a 1GB low‑power DRAM cache to provide consistent mainstream SATA performance.
Key features
- Capacity: 1TB (user capacity will be slightly lower after formatting).

- Sequential performance: up to 560 MB/s read and up to 530 MB/s write (typical maximums for the 1TB model).
- NAND & controller: Samsung V‑NAND (3‑bit MLC/TLC) with Samsung MKX controller and 1GB LPDDR4 cache.

Who it’s for
The 870 EVO 1TB is suitable for users seeking a straightforward, reliable capacity upgrade from spinning hard drives or older SSDs — especially for systems that are limited to SATA. It is appropriate for everyday computing, content storage and applications that benefit from consistent SATA throughput rather than the higher peak speeds of NVMe drives.
