SSSTC Launches ER4 Series Up to 16TB Enterprise SATA 6Gb 2.5-Inch SSD

Responding to the rapidly growing demand for high-density, low-latency storage in AI servers and data centers, Solid State Storage Technology Corp. (SSSTC), a subsidiary of Kioxia Corp., has introduced its next-gen enterprise SSD, the ER4 Series SATA SSD.

This series offers capacities of up to 16TB, making it one of the few SATA SSDs on the market to deliver such high density. It also features impressive random RW performance of 98K / 30K IOs, while the 8TB model achieves 98K / 55K IOs – combining large capacity with performance for AI inference, real-time analytics, and high-concurrency workloads.

The ER4 Series uses a 2.5-inch SATA 6Gb standard interface and supports hot-swapping, enabling direct replacement of traditional HDDs. This allows businesses to upgrade their storage seamlessly while maintaining existing infrastructure and optimizing cost efficiency. The lineup includes 16TB (15.36TB) and 8TB (7.68TB) models, both delivering sequential read/write speeds of up to 550MB/s and 530MB/s, respectively. Each model also provides 98K random read IOs, significantly enhancing processing capabilities in high-concurrency environments – particularly beneficial for OLTP workloads, AI inference, cloud platforms, and data analytics requiring low latency.

Beyond capacity and speed, the ER4 Series integrates multiple enterprise-grade data protection features, including end-to-end data protection, PLP(power-loss protection), secure erase, and AES 256-bit encryption (with optional TCG Enterprise support), ensuring data integrity both in transit and at rest.

The drives are built for long-term reliability, offering an MTBF of 3 million hours, a 10⁻¹⁷ UBER, and a 5-year product warranty – meeting the needs of enterprise environments requiring continuous, stable operation.

The ER4 Series is especially well-suited for online transaction processing (OLTP) systems, which demand high I/O performance, low latency, and strong data integrity. Powered by high-speed controllers and optimized firmware, the ER4 Series ensures stable performance under heavy transaction loads. It is also ideal for a range of applications including virtualization, cloud infrastructure, big data platforms, SMB NAS systems, backup environments, and video surveillance – helping organizations boost performance and storage efficiency without modifying existing hardware.
