MZ-76Q4T0BW Samsung 860 QVO MZ-76Q4T0 4TB SATA 2.5" SSD

High-Capacity 2.5in SATA Enterprise SSD for bulk tiers with the MZ-76Q4T0BW

The MZ-76Q4T0BW is a 4TB 2.5in SATA 6Gb/s internal SSD designed for read-intensive boot, secondary, and capacity-oriented storage in rack servers and embedded appliances. It aligns well with mainstream CPU platforms where the storage backplane is SATA/SAS and PCIe lanes are reserved for NICs, HBAs, and accelerators rather than NVMe bays.

Built on Samsung QLC 3D V-NAND with a 4GB cache, the MZ-76Q4T0BW provides predictable throughput up to 550 MB/s read and 520 MB/s write, with 4K IOPS suitable for OS images, content repositories, and warm datasets. The SATA interface simplifies integration into existing 2.5in hot-swap carriers, while endurance of 1440 TBW and a 0.3 DWPD rating support controlled write profiles typical of logging, patching, and periodic refresh cycles. For security-sensitive environments, the MZ-76Q4T0BW includes SED hardware encryption with AES-256 for at-rest protection.

Why Choose the MZ-76Q4T0BW?

The MZ-76Q4T0BW delivers a strong density-to-bay ratio for capacity tiers where NVMe is not operationally required, reducing cost and complexity while preserving solid-state latency benefits. With low idle power and consistent behavior under mixed enterprise workloads, the MZ-76Q4T0BW scales cleanly across fleet deployments as a standardised boot or secondary volume.

Samsung storage engineering focuses on controller firmware stability, NAND management, and qualification for continuous operation, supporting modern data centre expectations for reliability, security controls, and serviceability. The MZ-76Q4T0BW is specified for 1.5M hours MTBF and is engineered for consistent integration across server platforms.

Key Applications:

• Server boot and mirrored OS volumes
• Read-intensive VM templates and images
• Secondary storage for appliances
• Bulk warm-data tiers on SATA backplanes
• Encrypted at-rest data repositories
