The Micron M500 240GB (MTFDDAK240MAV-1AE12ABYY) is best suited for read-intensive server boot, edge caching, and embedded application workloads where 20nm MLC endurance and 72 TBW deliver stronger write tolerance than typical entry-class SATA TLC SSDs. With up to 500/250 MB/s throughput and 72,000/60,000 random IOPS, it provides a balanced low-latency profile for mixed small-block access while maintaining a cost-efficient 6Gb/s SATA deployment path.
With an endurance rating of 72 TBW, the MTFDDAK240MAV-1AE12ABYY can handle about 72,000 GB of total host writes over its service life, which is more than sufficient for typical OS boot, office, and general application workloads. In practical terms, for a light-duty system drive writing around 20 GB per day, this translates to roughly 10 years of use, giving procurement teams confidence for standard embedded or appliance-style deployments. For reliability, integrated power-loss protection helps preserve in-flight data and protects metadata integrity if power is interrupted unexpectedly, reducing the risk of corruption during sudden shutdowns. Its UBER rating of 1.0E-15 means an extremely low probability of unrecoverable bit errors during reads, and together with the 1.2 million-hour MTBF, it supports dependable long-term operation in business-critical environments.
1. The SATA 6Gb/s interface ensures broad compatibility with mainstream enterprise backplanes and enables straightforward drop-in upgrades for legacy server and storage platforms.
2. With up to 500 MB/s sequential read performance, the drive accelerates bulk data access such as OS boot, VM image loading, and backup restore operations in read-centric environments.
3. Delivering 72,000 random read IOPS, it supports faster response for metadata-heavy workloads like virtual desktop infrastructure, transactional indexing, and mixed-user application access.
4. Built with 20nm MLC NAND and rated for [dwpd] DWPD, the drive is engineered for sustained enterprise write activity where endurance consistency and data retention matter over long deployment cycles.
5. A typical latency of [latency] µs helps reduce storage response time variability, improving QoS for latency-sensitive applications such as databases and real-time service platforms.
Lower capacity reference: 120GB Higher capacity reference: 480GB Capacity positioning analysis: In this series, the 240GB model is the practical sweet spot. Compared with the 120GB version, it offers much better headroom for OS images, patches, logs, and application growth, reducing the risk of early capacity pressure. Compared with the 480GB option, it keeps acquisition cost and power footprint under tighter control while delivering essentially the same enterprise-class read/write and random IOPS profile. This makes 240GB especially well suited for a mid-sized virtualization cluster, such as boot and utility storage for about 40 to 60 infrastructure or edge service nodes.
Q: Is MTFDDAK240MAV-1AE12ABYY suitable for a write-heavy database server?
A: It is generally not ideal for a write-heavy database server. With 72TBW on a 240GB drive, its endurance is better suited to read-intensive or mixed workloads than sustained heavy writes.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: Based on 72TBW and 240GB capacity, the drive supports about 300 full-drive writes total. That equals roughly 0.16 DWPD over 5 years, or about 0.27 DWPD over 3 years.
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 mapping tables during sudden outages, which is critical for preventing corruption and maintaining storage integrity in server environments.
Q: What RAID level is recommended for this SSD?
A: For most business and database applications, RAID 10 is the preferred choice. It provides strong redundancy and better write performance than RAID 5 or RAID 6, especially for latency-sensitive workloads.
