MZ-77Q4T0BW Samsung 870 QVO 4TB SATA 2.5" SSD

High-Capacity 2.5in SATA Enterprise SSD featuring QLC 3D NAND and SED security with the MZ-77Q4T0BW

The MZ-77Q4T0BW is a 4TB 2.5in SATA (6Gb/s) internal SSD engineered for bulk capacity tiers in server and storage platforms where predictable latency and strong read throughput matter more than high write endurance. In mixed CPU environments, the MZ-77Q4T0BW integrates cleanly behind standard AHCI SATA controllers, enabling straightforward adoption in existing rack servers, hyperconverged nodes, and storage arrays without PCIe lane planning.

Built on 3D QLC NAND, the MZ-77Q4T0BW targets read-heavy datasets, application repositories, and general-purpose capacity expansion, delivering up to 560 MB/s sequential read and 98K random read IOPS for responsive access patterns. For architectures that reserve PCIe Gen4/Gen5 slots for GPUs, SmartNICs, or NVMe pools, the MZ-77Q4T0BW provides scalable SATA capacity while maintaining enterprise operability, including 1.5M hours MTBF and efficient power behavior for dense, always-on deployments.

Why Choose the MZ-77Q4T0BW?

The MZ-77Q4T0BW offers a pragmatic density-to-cost profile for capacity expansion and secondary tiers, pairing consistent SATA performance with device-level security to support compliance-driven deployments. With 1440 TBW endurance and 0.33 DWPD (3-year basis), the MZ-77Q4T0BW is well aligned to OS/application volumes, content distribution, and read-dominant virtualization footprints where predictable service levels and easy scaling are primary design goals.

Samsung designs this SSD platform around mature controller behavior, NAND management, and validation for long-life data center operation. The integration of AES-256 self-encrypting drive capabilities with TCG Opal 2.0, IEEE 1667, and Microsoft eDrive compatibility reflects alignment with modern endpoint and server security standards.

Key Applications:

• Bulk SATA SSD capacity tiers
• Read-heavy virtualization datastores
• OS and application volumes
• Secure endpoint and edge storage
• Content repositories and software distribution
