The Micron M500 240GB (MTFDDAK240MAV-1AE1ZA) is best suited for read-intensive boot, cache, and OS-drive roles in servers, network appliances, and industrial PCs, where its 2D MLC NAND delivers stronger write stability and predictable latency than typical client-grade TLC SATA SSDs in the same capacity class. With up to 500/250 MB/s throughput, 72,000/60,000 IOPS, and 72 TBW endurance, it offers a well-balanced SATA 6Gb/s platform for embedded and infrastructure deployments that prioritize reliability and sustained small-block responsiveness over peak capacity.
With an endurance rating of 72 TBW, this 240GB SSD can comfortably handle typical OS and office-style workloads over the long term, making it well suited as a boot or system drive. In practical terms, that is roughly equivalent to writing about 20GB per day for around 10 years, which is more than sufficient for many embedded, industrial, and light enterprise use cases. Its power-loss protection feature helps preserve in-flight data and critical metadata if power is interrupted unexpectedly, reducing the risk of corruption and improving system resilience. An UBER of 1.0E-15 means an extremely low unrecoverable bit error rate during reads, providing strong data integrity assurance for procurement teams evaluating dependable long-term storage.
1. The SATA 6Gb/s interface, paired with 500 MB/s sequential read performance, enables straightforward deployment in legacy enterprise servers while accelerating OS boot, log replay, and bulk data retrieval workloads.
2. With 72,000 random read IOPS, the drive can sustain responsive access to small-block data, improving VM density and reducing query wait time in read-heavy database environments.
3. A [dwpd] DWPD endurance rating means the SSD is built for sustained daily overwrite activity, helping enterprises maintain predictable lifespan under continuous write-intensive operation.
4. Built on 2D MLC NAND, the drive prioritizes stronger cell endurance and data consistency, making it well suited for business-critical applications that value reliability over peak capacity economics.
5. A typical latency of [latency] µs supports faster transaction acknowledgement and tighter QoS control, which is essential for enterprise systems that depend on stable low-latency storage behavior.
In the same series, the nearest lower capacity is 120GB and the nearest higher capacity is 480GB. These options generally deliver similar sequential read/write behavior and comparable random IOPS under typical enterprise workloads, with capacity being the main differentiator. At 240GB, this SSD sits in the sweet spot of the family. Compared with the 120GB model, it gives noticeably better space headroom for OS images, logs, patches, and application growth. Compared with the 480GB version, it keeps acquisition cost and fleet-wide replacement budgets under tighter control while preserving essentially the same enterprise-class performance profile. It is well suited for mid-scale virtualization clusters, such as boot and infrastructure storage for about 40 to 60 lightweight virtual machines.
Q: Is MTFDDAK240MAV-1AE1ZA suitable for a write-heavy database server?
A: MTFDDAK240MAV-1AE1ZA is generally not the best choice for a write-heavy database server. Its 72TB TBW and modest endurance make it better suited for read-intensive or mixed workloads.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: Based on 240GB capacity and 72TB TBW, it supports about 300 full drive writes total. Assuming a 5-year warranty, that equals roughly 0.16 drive 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 sudden power failure, reducing corruption risk and improving reliability in enterprise and server environments.
Q: What RAID level is recommended for this SSD?
A: For most server deployments, RAID 1 or RAID 10 is recommended with this SSD. These levels provide strong redundancy and consistent performance, especially compared with parity-based RAID in write-sensitive workloads.
