The Micron 5400 PRO 240GB (MTFDDAK240TGA-1BC1ZABYY) is purpose-built for write-intensive boot, logging, and edge-cache tiers that need enterprise SATA compatibility with stronger endurance, delivering 1.5 DWPD and 662 TBW in a compact 240GB footprint. Compared with typical read-centric SATA SSDs in the same capacity class, it provides a more balanced mixed-workload profile with up to 540/350 MB/s and 80,000/33,000 IOPS, making it a better fit for always-on infrastructure where steady write reliability matters more than headline capacity.
With an endurance rating of 662 TBW, this SSD can sustain approximately 181 GB of writes per day for 10 years, which is well above the write volume of a typical OS, boot, or office workload. In practical procurement terms, that means it can be used as a system drive for long-term deployment with a strong endurance margin and no concern about normal day-to-day write wear. Its power-loss protection (PLP) helps preserve in-flight data and metadata during an unexpected power interruption, reducing the risk of corruption and improving operational stability in enterprise environments. The specified UBER of 1.0E-17 indicates an extremely low unrecoverable bit error rate, supporting high data integrity, while the 3 million hour MTBF further reflects a design built for dependable continuous operation.
1. The SATA III interface ensures broad compatibility with mainstream enterprise servers and storage arrays, enabling straightforward deployment and predictable upgrade paths in legacy and mixed-infrastructure environments.
2. Sequential read performance of 540 MB/s accelerates large-file access, helping databases, virtual machine images, and backup datasets load faster during daily operations.
3. Random read capability of 80,000 IOPS supports highly concurrent transactional workloads, improving application responsiveness for OLTP, VDI, and metadata-intensive systems.
4. An endurance rating of 1.5 DWPD provides the write resilience needed for steady-state enterprise use, allowing consistent performance under sustained daily data churn.
5. Built with 3D TLC NAND, the drive balances capacity, cost efficiency, and reliability, making it well suited for read-heavy to mixed-use business workloads at scale.
Lower capacity reference: 120GB Higher capacity reference: 480GB At 240GB, this SSD sits in the sweet spot of the family. Compared with the 120GB option, it offers noticeably better headroom for OS images, logs, metadata, and growth over time, reducing early capacity pressure while keeping enterprise-class read/write and random IOPS behavior broadly similar. Compared with the 480GB model, it delivers a more balanced cost-per-node profile without paying for unused flash capacity. This makes 240GB especially well suited for medium-scale server boot pools, hypervisor hosts, or compact database and application clusters of around 20 to 40 nodes.
Q: Is MTFDDAK240TGA-1BC1ZABYY suitable for a write-heavy database server?
A: Yes. With 1.5 DWPD, 662 TBW endurance, 3D TLC NAND, and power loss protection, it is suitable for moderately write-intensive database workloads, especially where SATA reliability and data integrity matter.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated for 1.5 full drive writes per day. For a 240GB SSD, that equals about 360GB of writes daily, totaling approximately 662TB over the warranty period.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, it includes PLP. This feature helps protect in-flight data and metadata during sudden power failure, reducing corruption risk and improving reliability in servers, RAID arrays, and database environments.
Q: What RAID level is recommended for this SSD?
A: For business-critical or database use, RAID 10 is generally recommended because it combines strong performance with redundancy. If capacity efficiency matters more than speed, RAID 1 is also a common choice.
