OceanDisk 500P PCIe 5.0 3.84TB SM4 SED NVMe SSD — Marketing Copy
Secure Storage, Right-Sized — OceanDisk 500P 3.84TB SM4 SED NVMe SSD
Not every encrypted volume needs to be a capacity titan. The Huawei OceanDisk 500P 3.84TB brings the full SM4 self-encrypting disk platform — hardware-based, line-rate, zero-CPU-overhead encryption — to a capacity point that fits secure database volumes, regulated application tiers, and encrypted VM storage pools without overbuilding. PCIe 5.0 speed. SM4 compliance. Precisely 3.84TB.
The HSSD-O0525PL3T8S (SKU STLZ148SSD3840) encrypts every sector in silicon. Unlike software-layer encryption that steals CPU cycles and introduces latency jitter under load, the OceanDisk 500P’s hardware SM4 engine operates transparently at full PCIe 5.0 x4 throughput — well past 13 GB/s sequential. The drive performs as if encryption isn’t happening, because from the host’s perspective, it isn’t. The silicon handles it. The compliance audit passes. The performance baseline stays untouched.
At 1 DWPD across 3.84TB, this drive is optimized for read-intensive and capacity-optimized workloads where data-at-rest protection is a regulatory requirement, not an afterthought. Huawei’s intelligent disk platform runs computational offload — compression, data reduction, erasure coding — alongside the encryption pipeline, ensuring that security and efficiency operate in parallel, not in competition.
What the OceanDisk 500P 3.84TB SM4 SED delivers:
- PCIe 5.0 x4 NVMe 2.0 — next-gen throughput for encrypted workloads with zero performance penalty.
- Hardware SM4 SED — Chinese cryptographic standard compliance; line-rate encryption, no host CPU tax.
- 3.84TB capacity — right-sized for secure databases, regulated app tiers, and encrypted VM pools.
- 1 DWPD — purpose-matched endurance for read-intensive and capacity-optimized profiles.
- In-drive computational engine — compression and data reduction processed alongside encryption.
- Full power-loss protection — capacitor-backed; encrypted data integrity across any power event.
- 2.5-inch U.2 — standard enterprise hot-swap form factor.
For regulated industries that need SM4-compliant storage at every tier — not just the highest-density SKUs — the OceanDisk 500P 3.84TB is the drive that proves secure storage scales down as efficiently as it scales up.
OceanDisk 500P. Encrypted. Efficient. Every terabyte.
