4TB of Samsung V-NAND Performance in a 2.5″ SATA Form Factor

The Samsung 870 EVO MZ-77E4T0BW is a 4TB 2.5″ SATA III solid-state drive built for users who demand high-capacity, reliable storage in desktops, laptops, and NAS enclosures. Powered by Samsung’s proprietary MKX controller and Samsung V-NAND (TLC) technology, it delivers consistent sequential read speeds of up to 560 MB/s and sequential write speeds of up to 530 MB/s — maximising the throughput ceiling of the SATA III interface.

The 870 EVO uses Samsung’s Intelligent TurboWrite technology, which accelerates write performance by using a large SLC write buffer before transitioning to TLC cell storage. This makes it well-suited to sustained workloads including large file transfers, OS boot drives, and creative media libraries. The drive is rated for 2,400 TBW (Terabytes Written) at 4TB capacity, reflecting a strong endurance profile for a SATA-class consumer drive.

Samsung’s Magician Software provides real-time drive health monitoring, performance benchmarking, firmware updates, and data migration tools — giving you full visibility and control over your storage over its operational lifetime. The AES 256-bit hardware encryption (compatible with TCG Opal and IEEE 1667) adds a layer of data security without impacting drive performance.

Key Details & Benefits

• 4TB capacity — high-density storage for large OS installations, media libraries, and professional workloads
• Sequential read up to 560 MB/s / write up to 530 MB/s — maximises SATA III bandwidth
• Samsung V-NAND TLC — 3D cell stacking delivers greater density, lower power draw, and improved endurance vs. planar NAND
• MKX controller — Samsung’s in-house controller optimised for the 870 EVO’s NAND and workload profile
• Intelligent TurboWrite — large SLC write buffer accelerates burst and sustained write operations
• 2,400 TBW endurance rating — strong write durability for a high-capacity SATA drive
• AES 256-bit hardware encryption with TCG Opal 2.0 and IEEE 1667 support — data security without performance penalty
• 2.5″ SATA III form factor — compatible with desktop PCs, laptops, and most NAS devices
• Samsung Magician Software — health monitoring, performance optimisation, and firmware management
• Low power consumption — idle power of 30–50 mW, active power approximately 3.3W (typical)

Who Is This For

The Samsung 870 EVO 4TB is built for power users, creative professionals, and IT administrators who need a large, dependable SATA SSD for primary or secondary storage. It suits desktop workstation builds, laptop upgrades where NVMe is not supported, and NAS configurations requiring high-capacity drives with predictable endurance. Users migrating from HDDs who want a substantial, performance-consistent upgrade without switching platforms will find this drive a direct, high-impact replacement.

Specialisation

At 4TB, the 870 EVO sits at the top of Samsung’s SATA EVO lineup and justifies its price through the combination of Samsung’s own vertically integrated NAND fabrication, MKX controller engineering, and a 2,400 TBW endurance rating that substantially exceeds most competing SATA drives at this capacity. The hardware-level AES 256-bit encryption differentiates it from drives that rely on software-only encryption, which can impose CPU overhead. Samsung’s Magician ecosystem adds long-term operational value through active monitoring and over-time firmware support — features typically absent from budget SATA alternatives.

Comparison Advantage

Competing SATA SSDs at 4TB from brands such as Crucial and Western Digital typically match sequential read/write speeds at the SATA III ceiling, but lack Samsung’s vertically integrated NAND and in-house controller advantage, which translates to tighter manufacturing tolerances and more consistent real-world latency. The 870 EVO’s 2,400 TBW endurance at 4TB exceeds the Crucial MX500 4TB (1,000 TBW) and WD Blue 4TB (600 TBW) by a significant margin. The inclusion of TCG Opal 2.0 hardware encryption is absent from many direct competitors at this price tier, making the 870 EVO a stronger choice for security-conscious deployments.
