The Micron 5400 PRO 1.92TB (MTFDDAK1T9TGA-1BC16TAYY) is purpose-built for mixed-read/write virtualization clusters, OLTP databases, and content delivery edge nodes that need enterprise SATA compatibility with stronger endurance, delivering 1.5 DWPD and 5,256 TBW on reliable 3D TLC NAND. Compared with typical read-centric SATA SSDs in the same class, it provides a better balance of sustained write durability and predictable performance, with up to 540/520 MB/s sequential throughput and 95K/33K IOPS to keep legacy SATA server bays productive without moving to NVMe.
With an endurance rating of 5,256 TBW and 1.5 DWPD, this 1.92TB SSD is designed to handle very write-intensive enterprise workloads over its service life. In practical terms, for typical OS, application, boot, and mixed data workloads, this level of endurance means it can comfortably serve as a system or infrastructure drive for many years without write-life concerns. This drive also includes power-loss protection (PLP), which helps preserve in-flight data and metadata during an unexpected power interruption, reducing the risk of corruption and improving operational continuity. Its enterprise-class UBER of 1.0E-17, together with a 3 million hour MTBF, indicates an extremely low probability of unrecoverable bit errors and strong long-term reliability for business-critical environments.
1. The SATA 6Gb/s interface enables straightforward drop-in deployment across mainstream server backplanes, making it a low-risk upgrade path for legacy enterprise storage environments.
2. With sequential read performance of 540 MB/s, the drive accelerates large-file access such as backup restores, media streaming, and bulk dataset retrieval in read-heavy workflows.
3. Random read performance of 95,000 K IOPS helps sustain fast response times for virtualized workloads, OLTP databases, and metadata-intensive applications under concurrent access.
4. Rated for 1.5 DWPD, this endurance level supports steady daily write activity in enterprise environments while helping operators maintain predictable service life and replacement planning.
5. Built on 3D TLC NAND, the SSD balances capacity, cost efficiency, and reliability, making it well suited for scale-out data center deployments that need dependable mixed-workload performance.
Lower capacity reference: 960GB Higher capacity reference: 3.84TB In this product family, the 1.92TB model sits at the practical sweet spot. Compared with the 960GB option, it gives much better headroom for OS images, application binaries, log growth, and short-term data bursts, reducing early capacity pressure. Compared with the 3.84TB version, it usually delivers a better balance of acquisition cost, usable endurance efficiency, and enterprise-grade performance consistency, since sequential throughput and random IOPS are broadly similar across adjacent capacities. It is well suited for mid-scale virtualization clusters, such as storage for about 40 to 60 mixed-workload virtual machines.
Q: Is MTFDDAK1T9TGA-1BC16TAYY suitable for a write-heavy database server?
A: Yes. With 1.5 DWPD, 5256 TBW, 3D TLC NAND, and PLP, this 1.92TB SATA SSD is well suited for mixed-use and moderately write-heavy database workloads in enterprise environments.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: It is rated for 1.5 full drive writes per day over a 5-year warranty period. For a 1.92TB drive, that equals about 2.88TB of writes per day.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, it includes power loss protection. PLP helps preserve in-flight data and metadata during unexpected power failure, reducing corruption risk and improving reliability for transactional applications and RAID environments.
Q: What RAID level is recommended for this SSD?
A: RAID recommendation depends on workload and availability goals. RAID 10 is typically preferred for database servers because it offers strong performance, redundancy, and faster rebuilds than parity-based RAID levels.
