SK Hynix CD8 Enterprise SSD U.2 3.84TB

The SK Hynix CD8 Enterprise SSD in the U.2 2.5-inch form factor delivers 3.84TB of usable capacity over a PCIe Gen4 x4 NVMe interface, purpose-built for the demanding throughput and latency requirements of modern data-center infrastructure. Based on SK Hynix 128-layer TLC NAND flash and a high-performance NVMe 1.4 controller, the CD8 series achieves sequential read performance up to 7,000 MB/s and sequential write performance up to 4,200 MB/s, positioning it as a capable general-purpose enterprise drive for mixed read/write environments.

The CD8 3.84TB is designed to sustain consistent Quality of Service under heavy queue depths, with robust over-provisioning and advanced error-correction (LDPC) ensuring data integrity across the full rated endurance of 1 DWPD. Power-loss protection circuitry with onboard capacitance safeguards in-flight data during unexpected power events, a critical requirement for transactional and analytics workloads where consistency cannot be compromised. The drive supports end-to-end data path protection, SED (Self-Encrypting Drive) capabilities compliant with TCG Opal and AES-256 encryption, and a standard U.2 (SFF-8639) connector enabling direct hot-swap integration into mainstream 2.5-inch NVMe server and storage array backplanes.

As a sustained best-seller for general-purpose data-center storage, the CD8 3.84TB strikes a practical balance between capacity density, mixed-workload throughput, and operational endurance. Its thermal design and firmware-level workload management make it well suited for hyperscale rack deployments, all-flash arrays, and high-density server configurations where per-slot efficiency and predictable steady-state performance are equally important to peak benchmark numbers.

Ideal for

• General-purpose all-flash array (AFA) storage tiers requiring high sequential bandwidth and sustained mixed I/O performance across many concurrent virtual machines
• Relational and NoSQL database storage where consistent low-latency random read/write operations and data integrity under power-loss conditions are essential
• Hyperscale and cloud infrastructure deployments demanding high-capacity NVMe drives with PCIe Gen4 bandwidth to saturate modern server CPU and fabric interconnects
• AI and machine learning training pipelines that stage large datasets and checkpoint models, benefiting from 7,000 MB/s sequential read throughput to feed GPU clusters without bottleneck
• Virtualization hosts and VDI environments where storage consolidation onto high-capacity U.2 NVMe drives reduces slot count while maintaining per-VM IOPS headroom
• Backup-to-disk and fast-restore appliances leveraging the 3.84TB capacity and hardware AES-256 encryption to meet data-at-rest compliance mandates in regulated industries
