The Micron 5400 PRO 240GB (MTFDDAK240TGA-1BC1ZABYYR) is best suited for enterprise boot, OS, logging, and metadata-intensive edge or 1U server deployments that need a small-capacity SATA drive with unusually strong endurance, delivering 1.5 DWPD and 662 TBW in a 240GB footprint. Compared with typical same-class SATA SSDs that prioritize capacity over write life, it stands out by combining 3D TLC reliability with 540/350 MB/s throughput and 80K/33K IOPS, making it a stronger fit for sustained write-bearing infrastructure roles rather than simple read-mostly storage.
With an endurance rating of 662 TBW and 1.5 DWPD, the MTFDDAK240TGA-1BC1ZABYYR is designed to sustain consistent daily write activity over its service life, making it well suited for operating system, boot, logging, and mixed enterprise workloads. In typical system-drive usage, this level of endurance translates into many years of dependable operation, so buyers can expect long-term write durability without concern under normal deployment conditions. For enterprise reliability, this SSD includes power-loss protection (PLP), which helps preserve in-flight data and protect metadata integrity if power is interrupted unexpectedly. Its UBER of 1.0E-17, together with a 3 million hour MTBF, indicates a very low probability of unrecoverable bit errors and supports high data integrity and stable operation in business-critical environments.
1. The SATA III interface enables straightforward deployment in legacy and mixed-server environments, making it ideal for cost-efficient upgrades without changing existing backplanes or controllers.
2. Its strong sequential read performance accelerates OS boot, VM image loading, and large-file access, helping reduce wait time in read-heavy enterprise workloads.
3. High random read capability supports fast response under heavily concurrent small-block access, which is especially valuable for databases, virtualization, and transactional applications.
4. A 1.5 DWPD endurance rating provides the write durability needed for always-on business systems, balancing sustained reliability with practical total cost of ownership.
5. Built on 3D TLC NAND, the drive delivers enterprise-friendly capacity and power efficiency while maintaining the performance consistency required for mainstream data center use.
Lower-capacity reference: 120GB Higher-capacity reference: 480GB In this series, the 240GB model sits at the practical sweet spot for mainstream enterprise deployment. Compared with the 120GB option, it provides much better headroom for OS growth, patching, logs, swap, and application overhead, reducing the risk of early capacity pressure. Compared with the 480GB version, it preserves essentially the same enterprise-class read/write and random IOPS behavior while delivering a more attractive cost-per-node balance. It is especially well suited for medium-density clusters, such as boot and utility storage for around 40–60 virtualization hosts or infrastructure service instances.
Q: Is MTFDDAK240TGA-1BC1ZABYYR suitable for a write-heavy database server?
A: Yes. With 1.5 DWPD, 662 TBW, 3D TLC NAND, SATA III, and PLP support, this SSD is well suited for mixed-use and moderately write-heavy database server workloads.
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. For a 240GB SSD, that equals about 360GB daily, aligning with roughly 662TB written over a typical 5-year warranty.
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 outages, reducing corruption risk and improving reliability for enterprise or transactional environments.
Q: What RAID level is recommended for this SSD?
A: RAID 1 or RAID 10 is generally recommended, especially for databases and business-critical systems. These levels provide strong redundancy and better write performance than parity-based RAID configurations.
