The SSDPF2KX076T1N1 (D7-P5520 7.68TB) is a high-density PCIe 4.0 x4 NVMe SSD tuned for read-centric cloud storage, virtualization, and scale-out analytics, combining 7,100/4,200 MB/s sequential performance, up to 1.1M/200K IOPS, and 28 PBW endurance in a 1 DWPD profile. Compared with the previous SSDPF2KX076T1, this newer N1 revision brings a more advanced 144-layer 3D TLC generation and platform refinement, delivering stronger performance-per-watt and better sustained QoS consistency for mixed enterprise workloads at the same capacity point.
With an endurance rating of 28,000 TBW and 1 DWPD, the SSDPF2KX076T1N1 is designed to sustain one full drive write per day across its warranted life, which is more than sufficient for typical enterprise OS, boot, and mixed read/write infrastructure workloads. In practical terms, under normal system-disk or mainstream server usage, this level of endurance supports long-term deployment with a strong reliability margin and low concern over premature wear. For enterprise reliability, the drive includes Power Loss Protection (PLP), which helps preserve in-flight data and protects metadata integrity during unexpected power interruptions. Its UBER specification of 1.0E-17 indicates an extremely low uncorrectable bit error rate, giving buyers added confidence in data integrity for business-critical environments.
1. The PCIe Gen4 x4 NVMe architecture provides host-side bandwidth that keeps modern servers fed with data, making it well suited for virtualization clusters, analytics platforms, and AI pipeline staging.
2. Its sequential read performance enables very fast movement of large datasets, helping shorten backup restores, database warm-up, and content delivery load times.
3. The million-class random read capability supports dense mixed-workload environments, allowing more VMs, containers, or database sessions to be served without storage becoming the bottleneck.
4. The enterprise endurance profile is tuned for steady daily full-drive writes, giving operators predictable lifespan and lower replacement risk in read-centric cloud and business-critical deployments.
5. Built on high-layer 3D TLC NAND with very low typical latency, the drive balances capacity, efficiency, and responsive QoS for transactional applications that depend on fast and consistent access times.
Lower-capacity reference: 3.84 TB Higher-capacity reference: 15.36 TB Capacity positioning analysis: In this product family, the 7.68 TB model sits at the sweet spot between the 3.84 TB and 15.36 TB options. Compared with 3.84 TB, it gives materially better headroom for VM growth, container expansion, and longer refresh cycles without changing the platform footprint. Compared with 15.36 TB, it usually delivers the best balance of acquisition cost, usable capacity, and enterprise-grade performance consistency, since sequential throughput and random IOPS remain broadly similar across capacities. It is especially well suited for mid-scale virtualization clusters, such as hosting boot and application volumes for about 40 to 60 mixed-workload virtual machines.
Q: Is SSDPF2KX076T1N1 suitable for a write-heavy database server?
A: Yes, it can support database workloads well. With 1 DWPD, 28,000 TBW, PCIe 4.0 NVMe, and 75 µs typical latency, it fits mixed-use and moderately write-intensive enterprise servers.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated for 1 DWPD, meaning it can sustain one full 7.68 TB drive write per day across its warranty period, aligned with its 28,000 TBW endurance rating.
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, which is critical for enterprise databases, virtualization, and transactional workloads requiring integrity.
Q: What RAID level is recommended for this SSD?
A: RAID 1, 10, or 5/6 may be selected depending on performance and redundancy goals. For databases and virtualization, RAID 10 is commonly recommended for balanced write performance, protection, and low latency.
