Engineer's Note

Compared with the SSDPEDMW400G401, the SSDPEDMW400G4 strengthens the 750 Series value proposition with a PCIe 3.0 x4 NVMe design that delivers up to 2200/900 MB/s and 430,000/230,000 IOPS, giving read-intensive databases and virtualization hosts higher queue-depth performance and lower storage latency. Its 20nm MLC NAND, 127 TBW endurance, and 0.5 DWPD rating make it a more durable and performance-consistent 400 GB option than same-capacity SATA or client-grade SSDs in the same class.

Endurance & Reliability

With an endurance rating of 127 TBW, the SSDPEDMW400G4 can sustain 127 terabytes of cumulative writes, which is well above the write volume typically generated by OS, boot, and general application workloads. In practical terms, when used as a system or read-intensive enterprise boot drive, this level of endurance is sufficient to support many years of stable operation under normal daily usage. For enterprise reliability, the drive includes power-loss protection (PLP), which helps preserve in-flight data and metadata during an unexpected power interruption, reducing the risk of corruption and improving recovery confidence. Its UBER rating of 1.0E-16 means the probability of an uncorrectable bit error is extremely low, supporting dependable data integrity for business systems and procurement-grade deployments.

Technical Specs & Insights

1. The PCIe 3.0 x4 NVMe architecture, paired with 2200 MB/s sequential read performance, accelerates large dataset ingestion and shortens backup, boot, and VM image load windows in enterprise servers.
2. With 430,000 IOPS random read capability, the drive sustains responsive performance for metadata-heavy databases, virtualization clusters, and high-concurrency OLTP workloads.
3. A 0.5 DWPD endurance profile is well suited for read-centric enterprise deployments, helping reduce storage cost in content delivery, analytics, and scale-out infrastructure with moderate daily write pressure.
4. Built on 20nm MLC NAND, the SSD offers a balanced mix of reliability, consistent performance, and predictable lifecycle behavior required in always-on data center environments.
5. The 20 µs typical latency enables faster transaction acknowledgment and tighter QoS, improving application responsiveness for latency-sensitive services such as caching, index lookup, and real-time query processing.

Endurance & Reliability

Lower capacity reference: 200 GB Higher capacity reference: 800 GB Within this enterprise SSD family, the 400 GB model sits at the sweet spot. Compared with the 200 GB version, it offers much better headroom for OS images, logs, metadata, and application growth, reducing early capacity pressure in steady-state enterprise use. Compared with the 800 GB option, it keeps acquisition cost and cost-per-node more controlled while delivering broadly similar sequential throughput and random IOPS for typical deployments. This makes 400 GB especially well suited for mid-scale virtualization clusters, database boot volumes, or around 40–60 mixed enterprise application instances.
