Full technical description
The Micron 5400 PRO 3840GB combines Micron’s 176-layer 3D TLC NAND with a mature SATA III interface and an evolution of the Marvell-based controller architecture from the 5300 series. It is engineered for read-intensive, enterprise transactional workloads with a dedicated DRAM cache, full-path Power Loss Protection (PLP), and predictable steady-state latency; integrators note the SATA III interface remains a hard throughput bottleneck and recommend keeping firmware current for TCG Opal 2.0 encryption in mixed-vendor RAID deployments.
Key Specifications
- Interface: SATA III (6 Gb/s)
- Controller: Micron Custom S600 Series (Marvell-based architecture)
- NAND Flash: Micron 176-layer 3D TLC
- Sequential Read/Write: 540 MB/s / 520 MB/s
- Random 4K Read/Write: 95,000 IOPS / 33,000 IOPS
- Endurance Class: Read-Intensive (Approx. 1.5 Drive Writes Per Day)
- Features: Dedicated DRAM cache, Full Power Loss Protection (PLP), TCG Enterprise/Opal 2.0 support, Hardware-based AES 256-bit encryption
- MTTF: 3 million hours
Hardware Alternatives
- Samsung PM893: The primary direct competitor in the Data Center SATA space, targeting the same read-intensive workload tier but using Samsung’s proprietary controller and V-NAND architecture; performance differences are minimal due to the SATA bus limit.
- Solidigm (formerly Intel) D3-S4520: An enterprise option using 144-layer 3D TLC NAND that shares a focus on consistency and legacy infrastructure support; the Micron 5400 offers a generational advantage in NAND layering.
- Micron 5300 PRO: The direct predecessor with a nearly identical controller architecture and firmware foundation, easing qualification in servers validated for the 5300; the main distinction is the 5400’s migration to 176-layer NAND.
