The Micron 5100 PRO 240GB (MTFDDAK240TCB-1AR1ZA) is purpose-built for write-intensive boot, logging, and metadata tiers in edge servers and virtualization hosts, combining 2.5 DWPD endurance with 1,100 TBW in a compact SATA deployment. Compared with typical read-centric SATA SSDs in the same class, its 3D eTLC NAND and balanced 540/380 MB/s, 78K/30K IOPS profile deliver materially stronger sustained write durability and steadier mixed-workload performance where reliability matters more than raw capacity.
With an endurance rating of 1100 TBW and 2.5 DWPD, the MTFDDAK240TCB-1AR1ZA is built to handle sustained write-intensive use far beyond typical client or light server workloads. In practical terms, for common OS, application, and logging duties, this level of endurance can comfortably support many years of operation, making it a dependable choice as a long-life system or boot drive. Its enterprise-focused reliability is strengthened by power-loss protection (PLP), which helps preserve in-flight data and metadata if power is interrupted unexpectedly, reducing the risk of corruption and unplanned recovery events. The specified UBER of 1.0E-17 means the drive is designed for an extremely low rate of unrecoverable bit errors, supporting high data integrity in business-critical environments.
1. The SATA 6Gb/s interface ensures drop-in compatibility with mainstream enterprise backplanes and legacy server platforms, enabling low-risk SSD upgrades without changing the storage architecture.
2. Its sequential read performance accelerates large-block data access, helping shorten backup restores, VM image loading, and analytics dataset retrieval in read-heavy environments.
3. Strong random read capability supports high-concurrency transactional workloads, improving responsiveness for databases, virtual desktops, and metadata-intensive applications.
4. With enterprise-class write endurance, this drive is well suited for write-active deployments such as logging, caching, and mixed-use virtualization where sustained daily data churn is expected.
5. Built on 3D eTLC NAND, it balances cost efficiency with the reliability and consistency required for always-on datacenter operations.
In the same product family, the next lower capacity is 120GB and the next higher capacity is 480GB. The 240GB model sits at the sweet spot of the lineup: compared with 120GB, it gives meaningfully more headroom for OS images, logs, patch growth, and overprovisioning, reducing capacity pressure in always-on enterprise environments. Compared with 480GB, it delivers nearly the same enterprise-class sequential throughput and random IOPS while keeping acquisition cost and stranded capacity under better control. It is best suited for small to mid-sized virtualization clusters, such as boot and utility storage for about 40 to 60 application servers.
Q: Is MTFDDAK240TCB-1AR1ZA suitable for a write-heavy database server?
A: Yes. With 3D eTLC NAND, 2.5 DWPD endurance, 1100 TBW, and PLP support, this SSD is well suited for write-intensive database, logging, and transactional server workloads.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated for 2.5 full drive writes per day. For a 240GB SSD, that equals about 600GB of writes daily, consistent with its 1100 TBW endurance rating.
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 sudden outages, reducing corruption risk and improving reliability in enterprise and mission-critical applications.
Q: What RAID level is recommended for this SSD?
A: The recommended RAID level depends on your goal. RAID 1 suits high availability, RAID 10 is ideal for performance and redundancy, while RAID 5 or 6 favors capacity efficiency.
