The Micron M500 240GB (MTFDDAK240MAV-1AH12AC) is best suited for server boot volumes, virtualization hosts, and read-intensive edge appliances that need the proven endurance of 20nm MLC NAND, 72 TBW reliability, and strong SATA performance up to 500/250 MB/s with 72,000/60,000 IOPS. Compared with typical same-class SATA SSDs built for lower-endurance duty cycles, this model delivers a more durable and write-resilient profile, making it a better fit for always-on infrastructure where steady latency and long service life matter more than raw capacity.
With an endurance rating of 72 TBW, this 240GB SSD can sustain about 20GB of host writes per day for 10 years, which is more than sufficient for typical OS, boot, and general-purpose office workloads. In practical terms, for use as a system drive or light-read-intensive application drive, this endurance level provides solid long-term write headroom and dependable service life. 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. The specified UBER of 1.0E-15 indicates a very low unrecoverable bit error rate, supporting consistent data integrity and making the drive a reliable choice for business and embedded deployments.
1. The SATA 6Gb/s interface enables drop-in deployment across mainstream enterprise servers and storage arrays, making it a practical upgrade path for legacy infrastructure without platform changes.
2. With 500 MB/s sequential read performance, the drive accelerates large-file access such as VM image loading, backup restore, and analytics dataset retrieval.
3. Delivering 72,000 random read IOPS, it sustains responsive performance for read-intensive databases, virtualization clusters, and high-concurrency transactional workloads.
4. Built on 20nm MLC NAND and rated for [dwpd] DWPD, it provides the write endurance and data stability required for always-on enterprise applications with steady daily rewrite activity.
5. A typical latency of [latency] µs helps reduce storage response time, supporting more consistent QoS for latency-sensitive services such as OLTP and real-time application delivery.
Lower capacity reference: 120GB Higher capacity reference: 480GB Within this enterprise SSD family, the 240GB model sits at the sweet spot of practical deployment density. Compared with the 120GB version, it offers much better headroom for OS growth, patching, logs, swap, and application overhead, reducing early capacity pressure in always-on environments. Compared with the 480GB option, it preserves nearly the same enterprise-class sequential and random I/O behavior while delivering a more attractive cost-per-node balance. This makes 240GB especially well suited for small to mid-sized virtualization clusters, such as boot and utility storage for about 40 to 60 infrastructure or edge-service instances.
Q: Is MTFDDAK240MAV-1AH12AC suitable for a write-heavy database server?
A: Not ideally. While its 20nm MLC NAND and PLP improve reliability, the 72TBW endurance makes it better suited to read-intensive or mixed workloads than sustained write-heavy database applications.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: Based on 72TBW and 240GB capacity, it supports about 300 total full-drive writes. 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 outages, reducing corruption risk and improving storage integrity in enterprise environments.
Q: What RAID level is recommended for this SSD?
A: RAID 1 or RAID 10 is generally recommended, depending on capacity and performance needs. For database or business-critical workloads, RAID 10 offers the best balance of redundancy and speed.
