Micron 5400 PRO 7680GB

The Micron 5400 PRO 7680GB is an enterprise SATA drive built around Micron’s 176-layer 3D TLC NAND, paired with a Micron controller architecture and DRAM buffering. It is engineered to saturate the SATA III 6 Gb/s interface while prioritizing endurance and consistent I/O latency over peak burst throughput. In data center deployments it is often used to maximize capacity on legacy server backplanes without moving to NVMe. The 176-layer TLC offers higher write endurance and a more power-efficient profile compared to the previous 5300 series. Deployment teams should verify exact part numbers for security features: AES-256 hardware encryption is supported, but TCG Opal and TCG Enterprise support is SKU-specific.

Key Specifications

• Interface: SATA III (6 Gb/s)
• Sequential Speeds: 540 MB/s Read / 520 MB/s Write
• NAND Flash: Micron 176-layer 3D TLC
• Random Performance: ~95,000 IOPS Read / ~33,000 IOPS Write (4K)
• Endurance: ~1.5 DWPD (Drive Writes Per Day) / Read-Intensive classification
• MTTF: 3 million hours
• Encryption: AES-256 hardware encryption; optional TCG Enterprise/Opal 2.0 support

Hardware Alternatives

• Micron 5300 PRO: The direct predecessor, with a lower NAND layer count (96-layer) and lower density/endurance, but similar interface-limited performance.
• Samsung PM893: A primary competitor in the SATA data center read-intensive segment; similar role and performance profile.
• Solidigm (Intel) D3-S4520: A functional alternative using Intel floating-gate NAND; selection often depends on firmware qualification lists for specific server chassis since SATA limits performance.
