Samsung 870 EVO 4TB 2.5" SATA III Internal SSD

The Samsung MZ-77E4T0B/AM is a solid state drive with 4 TB of capacity that fits into any standard 2.5 inch bay and connects through the SATA 6 Gb/s interface. It brings the familiar 870 EVO series performance to desktops, laptops, and external enclosures that still rely on SATA.

Sequential read speeds reach up to 560 MB/s, while sequential write speeds climb to 530 MB/s. A 4 GB LPDDR4 cache working alongside the Samsung MKX controller helps those numbers stay consistent during large transfers, so game libraries, 4K video files, and application bundles move quickly and load without delay.

Samsung builds the drive on V-NAND that uses 3-bit MLC flash cells. The platform delivers an endurance rating of 2,400 terabytes written and a mean time between failures of 1.5 million hours, giving long-term peace of mind for daily use or heavy workloads. Built-in AES 256-bit hardware encryption with TCG Opal 2.0 support keeps sensitive data protected without reducing system performance.

Installation is straightforward: slide the drive into a desktop cage, a notebook bay, or an external enclosure, clone your existing data with Samsung migration software, and reboot. Full compatibility with Windows, macOS, and Linux makes the 870 EVO a practical upgrade for home users who want faster boot times, creative professionals who edit large media projects, and IT teams that manage mixed fleets of computers.
