Compared with the earlier SSDPE2MX400G401, the SSDPE2MX400G4 advances the DC P3500 platform with a more current PCIe 3.0 x4 NVMe deployment profile, delivering up to 2,200 MB/s read, 700 MB/s write, and 380K/25K random IOPS in a 400 GB footprint. Its 20nm MLC NAND and 219 TBW endurance make it a stronger fit for read-centric virtualization, web-scale caching, and analytics tiers that need lower latency and higher parallelism than SATA or legacy enterprise SSDs in the same capacity class.
With an endurance rating of 219 TBW and 0.3 DWPD, this SSD can sustain about 120 GB of host writes per day for 5 years, which is well aligned with typical OS, boot, logging, and office application workloads. In practical terms, if used as a system or boot drive with around 60 GB of writes per day, it can comfortably support roughly 10 years of service from an endurance perspective. For enterprise reliability, built-in power loss protection (PLP) helps preserve in-flight data and metadata during an unexpected power failure, reducing the risk of corruption and unplanned recovery events. Its UBER rating of 1.0E-17 means an extremely low unrecoverable bit error rate, supporting high data integrity and giving buyers added confidence for business-critical deployments.
1. The PCIe 3.0 x4 NVMe interface eliminates legacy storage bottlenecks, enabling faster VM boot, quicker database response, and better host CPU efficiency in enterprise servers.
2. Its strong sequential read performance accelerates large-file movement, helping analytics platforms, backup restore jobs, and media repositories complete data access tasks much faster.
3. The high random read capability supports dense virtualized workloads and read-heavy databases by sustaining responsive performance even when many small requests arrive at once.
4. With a light write endurance profile backed by mature 20nm MLC NAND, this drive is well suited for read-centric enterprise applications that need dependable data retention and lower cost per gigabyte.
5. The very low typical latency helps reduce application wait time, improving transaction consistency and delivering snappier performance for latency-sensitive services.
Lower-capacity reference: 200 GB Higher-capacity reference: 800 GB At 400 GB, this SSD sits at the sweet spot of the series. Compared with the 200 GB model, it offers meaningfully better capacity headroom for OS images, logs, swap, and application growth, reducing early refresh pressure. Compared with the 800 GB option, it keeps acquisition cost and per-node budget under tighter control while delivering essentially the same enterprise-class sequential throughput and random IOPS profile. This makes 400 GB especially well suited for mid-scale virtualization hosts, compact database nodes, or boot-plus-cache tiers in clustered infrastructure.
Q: Is SSDPE2MX400G4 suitable for a write-heavy database server?
A: SSDPE2MX400G4 is better suited for read-intensive or mixed workloads. With 0.3 DWPD and 219 TBW, it is generally not the best choice for highly write-heavy database environments.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated at 0.3 DWPD, meaning it can sustain about 0.3 full drive writes per day over its warranty period. For a 400 GB drive, that equals roughly 120 GB daily.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, it includes power loss protection. PLP is critical because it helps preserve in-flight data and metadata during sudden power failure, reducing corruption risk and improving storage reliability.
Q: What RAID level is recommended for this SSD?
A: The recommended RAID level depends on the application. RAID 1 is suitable for simple redundancy, while RAID 10 is preferred for better performance and fault tolerance in business-critical workloads.
