SK Hynix PS1101 U.2 Enterprise NVMe SSD

The SK Hynix PS1101 is a U.2 2.5-inch enterprise NVMe SSD built on PCIe Gen5 x4 architecture, targeting data centers and server environments that rely on traditional hot-swap SFF bays while demanding next-generation storage throughput. Leveraging SK Hynix's 238-layer TLC NAND flash and a purpose-built enterprise NVMe controller, the PS1101 achieves sequential read performance exceeding 14 GB/s and sequential write performance above 7 GB/s, representing a substantial leap over prior-generation Gen4 U.2 solutions. The drive is engineered to slot directly into existing U.2 backplane infrastructure, enabling operators to upgrade storage performance without platform redesign.

Architecturally, the PS1101 incorporates end-to-end data path protection including LDPC ECC, power-loss protection capacitors, and full hardware-based encryption (AES-256 with TCG Opal 2.0 support), ensuring data integrity in mission-critical deployments. The enterprise firmware implements advanced wear leveling, background media management, and thermal throttling algorithms optimized for 24/7 sustained workloads. A write endurance rating of up to 3 DWPD makes it well suited for write-intensive analytics, caching, and transactional database workloads that would rapidly exhaust consumer or read-intensive drives.

The PS1101 is targeted at infrastructure operators running virtualized environments, high-frequency transactional databases, AI/ML inference serving, and large-scale log analytics. Its compatibility with U.2 (SFF-8639) backplanes present in mainstream rack servers from major brands reduces integration complexity, while its NVMe 2.0 compliance ensures broad OS and hypervisor support. Available in capacities from 1.92 TB to 7.68 TB, the PS1101 provides scalable dense storage for workloads where both bandwidth and IOPS per drive matter.

Ideal for

• High-frequency OLTP database acceleration requiring low-latency random I/O and high sustained write endurance in rack-mounted database servers
• AI and machine learning inference serving where fast model loading and high sequential read bandwidth reduce time-to-first-token in NVMe-attached storage tiers
• Virtualization platforms with dense VM storage pools benefiting from high random 4K IOPS and consistent Quality of Service under mixed read/write workloads
• Real-time log analytics and streaming data pipelines that generate sustained high write throughput requiring drives rated for 3 DWPD continuous operation
• NVMe-oF (NVMe over Fabrics) storage disaggregation nodes where individual drive bandwidth and latency directly impact fabric-level aggregate performance
• Hyper-converged infrastructure (HCI) deployments replacing aging SATA or Gen3/Gen4 NVMe drives in existing U.2 server bays to increase storage tier bandwidth without chassis replacement
